Frequently Asked Questions Will this carburetor fit my Craftsman LT2000? If your Craftsman LT2000 has a Briggs & Stratton Intek engine in the 14-18HP range and the original carburetor part number matches one of the cross-references listed (799727, 698620, etc.), this carburetor will fit. Always verify your engine model number before ordering. Is this carburetor ready to run out of the box? Yes. It comes pre-adjusted from the factory. Install it, connect the linkages, and start the engine. You may want to fine-tune the idle speed screw after the engine warms up, but major mixture adjustments are typically not needed. Does this include the fuel solenoid? The carburetor includes the fuel solenoid mounting port. If your original carburetor had an anti-afterfire solenoid, you can transfer it from the old carburetor to this one. A new solenoid is not included. What's the difference between rebuilding and replacing? Rebuilding works well for carbs that are dirty but structurally sound. Replacement is better when the carburetor body is corroded, the throttle shaft bore is worn (causing vacuum leaks), or internal passages are permanently clogged. At iFJF's price point, replacement is often the more reliable long-term solution. Do I need any special tools? Basic hand tools are all you need: a socket set (typically 1/2" and 7/16"), flathead and Phillips screwdrivers, and needle-nose pliers for linkage clips. A can of carburetor cleaner is helpful for cleaning the mounting surface.

At iFJF Direct, we specialize in high-quality replacement parts backed by rigorous quality control. Each carburetor is individually tested for proper float operation and fuel flow before shipping. We stand behind every product with responsive customer support and a satisfaction guarantee. A new carburetor is often more cost-effective than rebuilding a corroded, gummed-up original — and gets your mower running right the first time. Frequently Asked Questions Q: Will this fit my Briggs & Stratton 550EX engine?A: Yes. This carburetor is compatible with all Briggs & Stratton 09P700 series engines, including the 550EX, 625EX, 675EX, and 725EXi 140cc models. Check your engine model number on the valve cover. Q: Does this carburetor come with gaskets?A: Yes. The carburetor arrives as a complete assembly including all necessary gaskets, float bowl, needle valve, and internal components. No parts to transfer from your old carburetor. Q: Do I need to adjust anything after installation?A: This carburetor comes pre-calibrated from the factory. In most cases, no additional adjustment is required. Simply install it, add fresh fuel, and start mowing right away. Q: My mower is hard to start — will a new carburetor fix this?A: Hard starting is one of the most common symptoms of a dirty or failing carburetor. Clogged jets, stuck floats, and deteriorated gaskets are the usual culprits. Replacing with a new 799584 carburetor typically resolves these issues. Q: How long does installation take?A: For most DIYers, installation takes 15-30 minutes. You'll need basic hand tools (screwdriver set, socket wrench) and a clean, well-lit work area. Q: Is this compatible with ethanol-blended fuel (E10)?A: Yes, the carburetor is compatible with E10 fuel. However, we recommend using fuel stabilizer or draining the carburetor if the mower will be stored for more than 30 days, as ethanol can cause varnish buildup in any small engine carburetor.

Overview The iFJF Carburetor 394352 is a direct OEM-spec replacement for Briggs & Stratton Intek V-Twin engines ranging from 14 to 18 horsepower. These engines power many of the most popular riding lawn mowers, zero-turn mowers, and lawn tractors from brands including Craftsman, Husqvarna, John Deere, Poulan Pro, and Toro. When your carburetor is gummed up from old fuel, has worn internal components, or simply won't hold a tune anymore, this replacement restores easy starting, smooth idle, and responsive throttle control. Rather than spending $80-120 on an OEM Briggs carburetor or $150+ at a small engine repair shop, this iFJF replacement delivers equivalent performance and fit at a fraction of the cost. Each carburetor is pre-adjusted and includes new mounting gaskets for a complete, hassle-free installation. Key Features Direct OEM Replacement — Exact fit for Briggs & Stratton Intek V-Twin 14HP-18HP engines, replaces part number 394352 and equivalents Pre-Adjusted — Factory-set for proper fuel mixture and idle speed; minor adjustment may be needed for your specific engine and altitude Complete Kit — Includes carburetor body, mounting gaskets, and fuel line fittings for a complete drop-in installation Restores Performance — Fixes hard starting, surging, stalling, rough idle, and poor throttle response caused by a failing carburetor Cost-Effective — Significant savings versus OEM Briggs carburetor ($80-120) or repair shop replacement ($150+) Bolt-On Installation — Replace in 30-45 minutes with basic hand tools; no special tuning equipment required Technical Specifications Specification Details Part Number 394352 Compatible Engine Briggs & Stratton Intek V-Twin 14HP-18HP Engine Series Intek 440000, 490000 Series Includes Carburetor Body, Mounting Gaskets, Fuel Fittings Installation Time 30-45 Minutes Fuel Type Gasoline (87+ Octane, E10 Compatible) Compatibility Brand Equipment Type Engine Craftsman, Husqvarna, John Deere, Poulan Pro, Toro & More Riding Mowers, Zero-Turn Mowers, Lawn Tractors Briggs & Stratton Intek V-Twin 14-18HP ⚠️ Verify Your Engine: Before ordering, confirm your engine model number (stamped on the valve cover or engine shroud). This carburetor is specifically for Intek V-Twin engines in the 440000 and 490000 series. NOT compatible with single-cylinder Intek engines or Vanguard V-Twin engines. Installation Guide Disconnect Battery & Fuel Line — Safety first: disconnect the spark plug wire and clamp/pinch off the fuel line Remove Air Filter Assembly — Remove the air filter housing to access the carburetor mounting bolts Disconnect Linkages — Carefully note position of throttle and choke linkages, then disconnect Remove Old Carburetor — Remove mounting bolts and extract the old carburetor; clean the mounting surface thoroughly Install New Carburetor — Position new gaskets, mount the iFJF 394352 carburetor, reconnect linkages exactly as they were Reassemble & Test — Reinstall air filter, reconnect fuel line and spark plug, start engine, and verify smooth operation FAQ Q: Will this carburetor fix my hard-starting mower?A: If the hard starting is caused by a gummed-up, clogged, or worn carburetor (which accounts for the majority of small engine starting issues), yes. If the problem is ignition-related (bad spark plug, coil) or compression-related, a new carburetor won't help. The most common symptom of carburetor failure is the engine only running with choke partially engaged. Q: Does it come pre-adjusted for my engine?A: Yes. Each carburetor is factory pre-set to approximate specifications for Briggs Intek V-Twin engines. Minor idle speed and mixture adjustments may be needed based on your specific engine, altitude, and climate. Most installations require no adjustment beyond the factory settings. Q: Will this fit my John Deere riding mower?A: If your John Deere mower uses a Briggs & Stratton Intek V-Twin engine (14-18HP), yes. Many John Deere 100 Series, D Series, and LA Series lawn tractors use these engines. Verify your engine model number before ordering — it's stamped on the valve cover. Q: Is ethanol fuel safe for this carburetor?A: This carburetor is compatible with E10 gasoline (up to 10% ethanol). For maximum carburetor life, we recommend: using fresh fuel (less than 30 days old), adding fuel stabilizer if the mower sits for more than 2 weeks, and running the carburetor dry before winter storage. Ethanol-blended fuel left sitting in the carburetor is the #1 cause of carburetor failure. Q: Do I need to replace the fuel filter at the same time?A: While not required, it's highly recommended. If the old carburetor was gummed up, debris may have been circulating in the fuel system. A new fuel filter ($5-10) is cheap insurance to protect your new carburetor from contamination. Q: How do I know if I need a new carburetor vs. just cleaning the old one?A: If the old carburetor is simply gummed from old fuel and less than 3-4 years old, cleaning may restore it. If the engine has more than 200 hours, the carburetor shows visible corrosion, or internal passages are permanently clogged, replacement is more reliable and often more cost-effective than the labor of multiple cleaning attempts. Q: Is this an OEM Briggs & Stratton part?A: This is a high-quality aftermarket replacement manufactured to Briggs & Stratton OEM specifications. It provides equivalent fit and performance at a significantly lower cost than the OEM-branded 394352 part. Q: Will this work with my existing air filter and intake?A: Yes. The mounting flange and intake interface match the OEM Briggs specification exactly. Your existing air filter assembly, intake manifold, and fuel line will connect directly to this carburetor without modification. 📚 Related Guides & Articles iFJF Guides & Resources — Expert Tips, Installation Tutorials & Buying Guides

High-Performance AVS2 Series 650CFM Carburetor The iFJF 1906 4-Barrel Carburetor brings legendary AVS2 performance technology to your engine build. Featuring the advanced annular flow booster design, this 650 CFM carburetor delivers exceptional fuel atomization for crisp throttle response and consistent power delivery. Whether you're upgrading a street cruiser, building a restomod, or preparing for weekend track days, the AVS2 platform provides the tunability and reliability that performance enthusiasts demand. The satin finish adds a premium look that complements any engine bay while providing enhanced corrosion resistance. Annular Booster Technology The defining feature of the AVS2 series is the annular discharge booster ring, which positions multiple fuel discharge ports around the entire circumference of each booster venturi. This design creates a finer fuel mist than traditional single-point boosters, resulting in more complete combustion, improved fuel economy at cruising speeds, and noticeably sharper throttle response. On the dyno, annular boosters have been shown to improve mid-range torque by 5-10 lb-ft compared to equivalent down-leg booster designs on a typical 350 CID small block.

It is perfectly suited for 327, 350, 383, and 400 CID engines in street performance and mild racing applications. Q: What does the annular booster design do?A: The annular discharge booster design provides superior fuel atomization compared to traditional down-leg boosters. This results in improved throttle response, better fuel economy at cruise, and more consistent air-fuel mixture across all RPM ranges. Q: Does this carburetor come with an electric choke?A: Yes, the iFJF 1906 features an integrated electric choke for reliable cold starts. Simply connect to a 12V ignition-switched power source and the choke will automatically adjust based on engine temperature. Q: Is this a square bore or spread bore carburetor?A: This is a square bore (4150-style) carburetor designed to bolt directly onto square bore intake manifolds. It can also be used with spread bore manifolds using an adapter plate (sold separately). Q: What is the satin finish and why does it matter?A: The satin finish is a premium aesthetic treatment that provides a semi-gloss, non-reflective surface. It resists fuel stains and corrosion better than raw aluminum while maintaining a classic performance look that complements any engine bay. Q: Is tuning required out of the box?A: The carburetor comes with baseline calibration suitable for a typical 350 CID engine at sea level. Minor adjustments to idle mixture screws, accelerator pump, and possibly jet changes may be needed based on your specific engine combination, elevation, and performance goals. Q: What makes this different from the standard AVS series?A: The AVS2 series features the upgraded annular flow booster design, improved fuel metering circuits, and a revised air valve system that provides more precise secondary engagement compared to the original AVS design, resulting in smoother power delivery and better mid-range torque.

The original Rochester Quadrajet was a brilliant design but suffered from warped bodies, leaky well plugs, and worn throttle shafts after decades of service. Our 1901R replacement addresses all these weaknesses with modern CNC machining, improved aluminum alloy, and precision calibration. You get the signature Quadrajet sound and performance without the headaches of a 50-year-old core. Each unit is wet-flow tested before leaving the factory. We stand behind every carburetor with our satisfaction guarantee. Installation Tips Verify intake manifold is square bore pattern (not spread bore without adapter) Set idle mixture screws to 2-1/2 turns out as starting point Use a phenolic spacer to reduce heat soak on hot starts Check fuel pressure — Quadrajets prefer 5-6 PSI maximum Connect choke cable to manual choke linkage before final mounting Torque mounting bolts to 12-15 ft-lbs in a crisscross pattern Frequently Asked Questions Q: Will this fit my 1969 Camaro with a 350?A: Yes. This 1901R Quadrajet 4MV is a direct replacement for 1966-1973 Chevy 327-454 engines with a square bore intake manifold. Your 1969 Camaro 350 is a perfect match. Q: Does this carburetor come with a gasket?A: Yes, a base gasket is included. We recommend using a quality fiber gasket or 1/4" phenolic spacer for best results. Q: Is this a rebuilt original or brand new?A: This is a 100% brand new carburetor — not a remanufactured or rebuilt core. No core charge, no waiting for a rebuild. Q: Do I need an adapter to install this on a spread bore manifold?A: This is a square bore carburetor. If your intake manifold is a spread bore (common on later Quadrajets), you will need a square-to-spread bore adapter plate (sold separately). Q: How do I adjust the manual choke?A: The choke lever connects to a standard choke cable (not included). Route the cable through your firewall and mount under the dash. Pull to close choke for cold starts, push to open as engine warms. Q: What's the difference between vacuum secondary and mechanical secondary?A: Vacuum secondaries open based on engine load — they only engage when the engine can actually use the extra air/fuel. This prevents bogging and improves driveability on the street compared to mechanical secondaries. Q: Does this carburetor have EGR provisions?A: No. This carburetor does not include EGR provisions, making it ideal for non-emissions applications, off-road use, or vehicles with EGR deleted.

The Quadrajet was GM's workhorse carburetor for over two decades. But original units are now 50+ years old — warped air horns, leaking well plugs, and worn throttle shafts are common problems. Our 1901R gives you the legendary Quadrajet design with modern manufacturing: precision CNC-machined metering circuits, properly sealed well plugs, and a brand new casting that hasn't been through 50 years of heat cycling. The result is a carburetor that starts easier, idles smoother, and delivers the fuel economy these trucks were known for when new. Frequently Asked Questions Q: Will this fit my 1970 C10 with a 350?A: Yes, this is a direct replacement for your 1970 C10 350. The 1901R bolts to the factory Quadrajet intake manifold and uses the same throttle linkage and fuel line connection. Q: Do I need to change my intake manifold?A: No. The 1901R fits the factory cast iron Quadrajet intake manifold found on 1968-1973 GM trucks. No adapter needed. Q: How do I connect the throttle linkage?A: The throttle lever accepts the factory GM throttle cable and transmission kickdown cable (TH350/TH400). The geometry matches OEM specifications. Q: Is this carburetor good for towing?A: Absolutely. The Quadrajet's small primaries provide excellent fuel economy during cruise while the massive secondaries deliver full power for towing and hauling heavy loads. Q: Can I convert this to electric choke?A: This model is manual choke only by design. If you prefer electric choke, see our other Quadrajet-style options. Q: What fuel pressure do I need?A: 5-6 PSI maximum. Stock mechanical fuel pumps are ideal. If using an electric pump, install a regulator set to 5 PSI.

Product Overview The iFJF 1901 Thunder AVS2 500 CFM carburetor is the next evolution in the Thunder carburetor lineup, featuring enhanced annular flow boosters for even finer fuel atomization. With 12V electric choke, non-EGR calibration, and a clean satin finish, this 4-barrel is purpose-built for small cubic-inch V8 and V6 engines where crisp throttle response matters more than maximum CFM. Ideal for restomods, street rods, and daily drivers with 260-327 CID engines. Key Features AVS2 Annular Boosters — Second-generation annular discharge booster design with improved fuel distribution across all 8 discharge holes. Noticeably smoother idle and better tip-in response than first-gen designs. 500 CFM Precision Calibration — Calibrated specifically for 260-327 CID small block V8s. Avoids the tuning headaches of oversized carburetors on small engines. Electric Choke — 12V automatic choke with adjustable housing. Cold starts in any weather without a manual choke cable. Non-EGR Design — No EGR port or provisions. Ideal for pre-emissions vehicles, off-road builds, and engines with EGR systems removed. Satin Finish Aluminum — Clean, understated appearance that doesn't yellow or discolor. Resists fuel staining and corrosion. Quick-Change Secondary Metering — Swap secondary rods in under 60 seconds with a screwdriver — no carb removal needed. Compatibility Engine Displacement Best Match Chevy Small Block 262-327 CID Mild street cam, stock heads, dual-plane intake Ford Windsor 260-302 CID Stock to mild build, great for early Mustangs Jeep V8 304-360 CID Good for Jeep CJ/Wagoneer with square bore manifold AMC V8 290-304 CID Direct fit on square bore aftermarket intakes Specifications Parameter Value Part Number 1901 CFM Rating 500 CFM Barrel Type 4-Barrel Square Bore Choke 12V Electric Primary Jet 0.095" Secondary Jet 0.095" EGR Non-EGR Finish Satin Aluminum Why AVS2? The AVS2 upgrades the classic Thunder/Edelbrock design with annular flow boosters — the same technology used in high-end racing carburetors. Instead of a single fuel discharge point, each booster has 8 precision-drilled holes that create a cone-shaped fuel mist. The result is more complete combustion at part throttle, smoother transitions, and fuel atomization that rivals EFI at a fraction of the cost. Frequently Asked Questions Q: What's the difference between AVS and AVS2?A: The AVS2 uses annular discharge boosters (8-hole ring) instead of standard down-leg boosters, providing finer fuel atomization. This results in smoother idle, better throttle response, and improved part-throttle fuel economy. Q: Does non-EGR mean I can't use it on a street car?A: Non-EGR simply means the carburetor does not have exhaust gas recirculation ports. It works perfectly on street cars — especially pre-1975 vehicles that didn't have EGR or vehicles where EGR has been removed for off-road use. Q: Can I use this on a 350 Chevy?A: A 500 CFM carburetor may be slightly restrictive for a built 350 at high RPM. For stock or mild 350s, it will work but may limit top-end power. For performance 350+ builds, consider our 600-650 CFM options. Q: Does this come with a fuel line and filter?A: A 5/8"-20 inlet fitting is included. The fuel line and inline filter are sold separately — we recommend a 3/8" braided line with serviceable filter. Q: How do I set the idle mixture?A: Start both mixture screws at 2 turns out. With engine warm and choke fully open, turn each screw in slowly until RPM drops, then back out 1/2 turn. Adjust idle speed to 700-800 RPM.

The factory Solex 34 PICT-3 carburetor was adequate when new but is now notorious for warped throttle bodies, clogged idle circuits, and difficult cold starts. The Weber IDF design has been the gold standard for air-cooled VW performance since the 1970s. It offers superior tunability with replaceable jets, a more robust accelerator pump circuit, and dramatically improved throttle response. Whether you're restoring a daily driver or building a weekend cruiser, this carburetor transforms how your vintage VW drives. Installation Tips Use new paper gaskets on both sides of the phenolic spacer block Set idle mixture screws at 1 turn out from seated as starting point Verify fuel pressure at 2.5-3.0 PSI — mechanical pumps may need a regulator Base idle speed: 850-900 RPM on air-cooled engines Check for vacuum leaks at intake boots and manifold end castings before tuning With a 009 mechanical advance distributor, set timing to 28-32° BTDC at 3000+ RPM Frequently Asked Questions Q: Will this fit my 1974 Super Beetle with stock engine?A: Yes. The 18990035 Weber 44 IDF is a direct bolt-on replacement for the stock Solex carburetor on your 1974 Super Beetle 1600cc. It bolts to the factory intake manifold center section. Q: Do I need to change my distributor when installing this carburetor?A: The Weber 44 IDF works well with both vacuum-advance (SVDA) and centrifugal-advance (009) distributors. If using a 009, make sure the vacuum port on the carb is capped. Q: Is this carburetor too big for a stock 1600cc engine?A: The 44 IDF is properly sized for stock to mild 1600cc engines when properly jetted. It comes pre-calibrated for 1600cc. If upgrading to 1776cc or larger, you may want to increase main jet sizes. Q: What air filter fits on this carburetor?A: The integrated air horn accepts standard IDF-style air filter assemblies. Low-profile oval filters (commonly available for Beetle engine bays) fit perfectly. Q: Does this carburetor work with dual carb setups?A: This carburetor is designed for single center-mount applications. For dual carb setups, consider dual 40 IDF or 44 IDF kits with appropriate manifolds. Q: Will I need to re-jet for my elevation?A: At elevations above 4,000 ft, you may want to reduce main jet size by 5-10 numbers. Below 4,000 ft, the factory jetting will work well.

Product Overview The iFJF 18025 (1825) Thunder AVS 650 CFM 4-barrel carburetor is purpose-built for off-road performance. Featuring annular discharge boosters, manual choke control, and a durable satin-finish aluminum body, this carburetor delivers consistent fuel metering through extreme angles, rough terrain, and high-vibration environments. Whether you're rock crawling, mud bogging, or trail riding, the Thunder AVS keeps your engine running strong when the trail gets nasty. Key Features Annular Discharge Boosters — Superior fuel atomization at low and mid-range RPM compared to traditional down-leg boosters. Eight discharge holes per booster ensure an even fuel cone for crisp throttle response. Off-Road Optimized — Spring-loaded needle and seat design and tuned float levels resist fuel slosh at steep angles — no more stalling on inclines. Manual Choke — Reliable cable-operated choke. No electrical connections needed — perfect for off-road rigs with stripped-down wiring. 650 CFM Flow — Sweet spot for small block V8s (283-400 CID) and mild big blocks. Enough airflow for performance without over-carbureting. Satin Finish Aluminum — Corrosion-resistant die-cast aluminum body with a clean satin appearance that stays looking good even after mud and power washing. Square Bore Pattern — Direct fit on most aftermarket intake manifolds and factory 4-barrel square bore intakes. Compatibility Application Engine Size Notes Small Block Chevy (283-400) 283-400 CID Best for 327, 350, 383, 400 with mild cam Small Block Ford (289-351W) 289-351 CID Ideal for 302 and 351W builds Mopar Small Block (318-360) 318-360 CID Fits LA and Magnum engines Mild Big Block V8 396-454 CID Suitable for stock to mild big block builds Off-Road / 4x4 Vehicles Any V8 Optimized for steep angles and rough terrain Specifications Parameter Value Part Number 18025 (also referenced as 1825) CFM Rating 650 CFM Barrels 4-Barrel Square Bore Choke Type Manual Choke Booster Type Annular Discharge Primary Jet 0.095" Secondary Jet 0.098" Body Material Die-Cast Aluminum (Satin Finish) Throttle Bore 1-11/16" Primary / 1-11/16" Secondary Why Choose iFJF Thunder AVS for Off-Road? Standard street carburetors fail off-road. Fuel slosh causes flooding on steep climbs. Vibration shakes floats out of adjustment. Dust clogs vent tubes. We designed the Thunder AVS from the ground up for the abuse of off-roading — sealed vent tubes, spring-loaded needles, and a float bowl design that keeps fuel where it belongs even at 45-degree angles. The annular boosters provide better low-end torque response, critical for crawling over obstacles at idle speed. If you've ever had your rig die mid-climb because the carb flooded out, this is the fix. Installation Notes Standard square bore flange — fits Edelbrock Performer, RPM, and most aftermarket intakes Use a 1/4" heat insulator gasket to prevent heat soak on hot engines Route manual choke cable away from exhaust manifolds/headers Set idle mixture screws at 1-1/2 turns out as baseline Fuel pressure: 5.5 PSI maximum (use regulator if mechanical pump exceeds this) Frequently Asked Questions Q: Will this carburetor work at extreme angles while rock crawling?A: Yes. The Thunder AVS is specifically designed for off-road use with spring-loaded needle and seat assemblies and optimized float levels that resist fuel slosh at angles up to 45 degrees. Q: Can I use this on a street-driven truck too?A: Absolutely. While optimized for off-road, this carburetor performs excellently on the street. The annular boosters deliver crisp throttle response for daily driving. Q: What's the difference between annular and down-leg boosters?A: Annular boosters have 8 small discharge holes arranged in a ring, providing finer fuel atomization and better low-RPM torque. Down-leg boosters have a single discharge point and are typically used in race-only applications. Q: Does this come with mounting hardware?A: Yes — mounting studs, nuts, washers, and a base gasket are included in the box. Q: What fuel line size do I need?A: The fuel inlet accepts a 5/8"-20 thread fitting. We recommend 3/8" fuel line for engines up to 400 HP. Q: Will this fit my Jeep CJ with a Chevy 350 swap?A: Yes — this is an excellent choice for a Chevy 350 swapped into a Jeep CJ, YJ, or TJ. The off-road design handles the angles you'll encounter on the trail.

The 600 CFM Performer has been the go-to street performance carburetor for decades. Our 1806 builds on that legacy with modern manufacturing precision. The air valve secondary design is inherently smoother than mechanical secondaries for street driving — you don't get the sudden "hit" that can break tires loose unexpectedly on wet pavement. Combined with the 12V electric choke, this is the set-it-and-forget-it carburetor that starts reliably and drives smoothly from cold mornings to hot summer afternoons. Frequently Asked Questions Q: Will this fit my 350 Chevy with an Edelbrock Performer intake?A: Yes. The 1806 has a standard square bore flange that matches the Edelbrock Performer, Performer RPM, and most other aftermarket intakes. Direct bolt-on — no adapter needed. Q: What's air valve secondary vs. vacuum secondary?A: Air valve secondaries use a spring-loaded flap above the secondary throttle plates. As airflow increases, the valve opens progressively — providing smoother engagement than mechanical secondaries and more precise control than pure vacuum secondaries. Q: Will this work with my TH350 automatic transmission?A: Yes. The throttle lever includes provisions for GM TH350, TH400, 700R4, and 200-4R kickdown cables. Ford AOD and C4/C6 linkages are also supported with the correct bracket. Q: Does non-EGR mean it won't pass emissions?A: Non-EGR carburetors are intended for pre-emissions vehicles (generally pre-1975), off-road vehicles, or vehicles where the EGR system has been removed. Not for use on emissions-controlled vehicles where EGR is required by law. Q: Can I use this on a marine engine?A: No. Marine engines require USCG-approved carburetors with specific safety features (sealed overflow, J-tube venting). Use only marine-rated carburetors on boats. Q: What timing should I run with this carburetor?A: For most small block Chevy engines, start with 10-12° initial timing and 34-36° total mechanical advance by 3,000 RPM. Adjust vacuum advance to provide 10-12° additional under light cruise.
