Carburetor

Autolite 1100 / 1101 1-Barrel Carburetor — Complete Unit, Pre-Tuned & Ready to Run This is a fully assembled, pre-tuned Autolite 1100 carburetor — not a rebuild kit or individual parts. The iFJF Autolite 1100 delivers factory-spec performance for Ford's legendary 200 cubic inch (3.3L) inline-six engine found in 1963–1967 Mustangs, Falcons, Fairlanes, Comets, and Econoline vans. Each unit is pre-adjusted at the factory for the correct air-fuel mixture and idle speed, so you can unbolt your old carb, bolt this one on, and drive the same day. No tuning, no guesswork, no frustration. Key Features & Benefits Complete, Pre-Tuned Carburetor Forget sourcing gaskets, chasing rebuild parts, or spending hours trying to tune a worn-out core. This is a complete replacement carburetor — factory-adjusted for the 200ci inline-6. The throttle plate, choke mechanism, float, and all internal passages are brand new and calibrated to Ford's original specifications. Manual Choke — Period Correct Features the correct manual choke setup as used on 1963-1967 Ford 200ci six-cylinder engines. The choke cable attachment point matches the factory configuration, preserving the original driving experience and under-hood appearance. Direct Bolt-On Fitment The mounting flange, throttle linkage, fuel line connection, and vacuum port are in the exact same positions as the original Autolite 1100/1101. No adapter plates, no modified linkages, no custom fuel lines. Unbolt the old, bolt on the new, connect three things, and start. Technical Specifications Specification Detail Model iFJF Autolite 1100/1101 Carburetor Type 1-Barrel Downdraft Choke Type Manual Engine Ford 200ci (3.3L) Inline-6 Year Range 1963-1967 Venturi Size 1.20" (30.5mm) Mount Type 3-Bolt Flange Compatible Ford Models 1964½–1967 Ford Mustang 200ci 3.3L I6 1963–1967 Ford Falcon 200ci I6 1963–1967 Ford Fairlane 200ci I6 1963–1967 Mercury Comet 200ci I6 1963–1967 Ford Econoline Van 200ci I6 1965–1967 Ford Ranchero 200ci I6 Installation Disconnect the battery. Remove the air cleaner. Disconnect the fuel line at the carburetor inlet. Disconnect the manual choke cable, throttle linkage, and the vacuum advance line. Remove the three mounting nuts (1/2" wrench). Lift off the old carburetor and mounting gasket. Clean the intake manifold mounting surface thoroughly. Place the new gasket on the manifold studs. Position the new carburetor and tighten the mounting nuts evenly (12-15 ft-lbs). Reconnect the fuel line (use a flare nut wrench to avoid rounding the fitting), throttle linkage, choke cable, and vacuum line. Reconnect the battery. Crank the engine — it should start with minimal cranking. Let it warm up and check the idle speed (550-600 RPM in Drive for automatic, 600-650 RPM for manual). Tuning Notes Idle Mixture: The idle mixture screw is pre-set but can be fine-tuned. With the engine warm, turn the screw in until the RPM drops, then back out 1/2 turn. Final setting should produce the highest steady idle. Float Level: Pre-set from the factory. If adjustment is needed: with the top removed and gasket in place, the float should be 1-5/32" from the gasket surface. Frequently Asked Questions Is this carburetor really pre-tuned? Yes. Each unit is bench-tested for proper float level, throttle plate operation, and base mixture setting before packaging. Most installations require only a minor idle speed adjustment to account for differences in engine condition, altitude, and transmission type. Will this fit a 170ci engine? This carburetor is calibrated for the 200ci (3.3L) inline-6. While it physically bolts onto a 170ci manifold, the jetting and venturi size may be slightly rich for the smaller displacement. It will run but may need re-jetting for optimal fuel economy on a 170ci engine. Does this fit a 1968 or later 200ci? 1968 and later Ford 200ci engines used different emissions equipment and carburetor designs. This carburetor is optimized for 1963-1967 non-emissions applications. It may physically fit later engines but linkage and vacuum port configurations differ. What's the difference between the 1100 and 1101? The Autolite 1101 is essentially the same carburetor with a slightly larger venturi and different jetting for higher-output applications. This unit works for both 1100 and 1101 replacement applications on the standard 200ci engine.

Marine Electric Choke Assembly for Mercruiser 2-Barrel Mercarb The iFJF 18-7665 marine electric choke assembly is a direct replacement for Mercruiser 2-barrel Mercarb carburetors on 3.0L 4-cylinder sterndrive engines. This choke automatically enriches the fuel mixture during cold starts using a 12V electric heating element — eliminating the need for manual choke cables or operator intervention. Replaces OEM 70125A-1 and Sierra Marine 18-7665. Key Features Automatic Electric Operation: 12V heating element progressively opens the choke plate as the engine warms up — no cables, no manual adjustment. Direct OEM Replacement: Precision-fit for Mercruiser 2-barrel Mercarb carburetors. Replaces OEM 70125A-1 and Sierra 18-7665. Improved Cold Starts: Provides the correct cold-start fuel enrichment for instant starting and smooth warm-up, even after extended storage. Corrosion-Resistant Construction: Designed for the harsh marine engine compartment environment — resists salt air corrosion and humidity damage. Plug-and-Play Installation: Connects to the existing 12V ignition-switched power source. Uses the same mounting pattern as the original choke. Compatibility Engine Carburetor Application Mercruiser 3.0L (181 ci) 2-Barrel Mercarb Sterndrive, 4-cylinder, various years Mercruiser 3.0LX 2-Barrel Mercarb Sterndrive, 4-cylinder Mercruiser 3.0L MPI (Verify) N/A — Fuel Injected ❌ Not Compatible — MPI models don't use carburetors Cross-Reference Brand Part Number Sierra Marine 18-7665 Mercruiser OEM 70125A-1 Signs of a Failing Electric Choke Hard cold starting: Choke doesn't close fully — engine cranks excessively before firing. Engine stalls when cold: Choke opens too quickly, leaning out the mixture before the engine is warm. Black smoke / rich running when warm: Choke stays partially closed — heating element has failed. Rough idle after cold start: Choke opening inconsistently due to intermittent electrical connection. High idle persists too long: Heating element weak — choke takes excessive time to fully open. Installation Overview Disconnect battery negative terminal (safety first in marine environments). Remove the flame arrestor / air cleaner assembly. Disconnect the old choke electrical connector. Remove the old choke assembly (typically 2-3 screws on the carburetor housing). Install the new iFJF 18-7665 choke, ensuring the choke plate linkage engages correctly. Connect the electrical lead to 12V ignition-switched power. Verify choke operation: cold engine → choke plate should be nearly closed. Apply 12V → plate should slowly open over 2-5 minutes. Frequently Asked Questions Q: Does this fit all Mercruiser 3.0L engines?A: This choke fits Mercruiser 3.0L engines with the 2-barrel Mercarb carburetor. It does NOT fit 3.0L MPI (multi-port fuel injection) models, which don't use a carburetor or choke. Verify your engine has a carburetor before ordering. Q: How do I test my existing choke?A: With a cold engine, remove the flame arrestor. The choke plate should be nearly closed. Start the engine and observe — the plate should slowly open over 2-5 minutes. If it stays closed after 5+ minutes, the heating element is dead. If it snaps open immediately, the bimetal spring is broken. Q: Does this require 12V constant or switched power?A: Connect to ignition-switched 12V (only powered when the key is ON). Connecting to constant 12V will keep the choke heating element energized and drain your battery. Q: Can I adjust the choke opening speed?A: The opening speed is determined by the heating element and bimetal spring — not user-adjustable. However, you can adjust the initial choke plate gap via the choke housing rotation. Mark the original position before removal. Q: Is the gasket included?A: If the kit includes a mounting gasket, it will be in the package. If your original gasket is in good condition, it can be reused.

Carburetor Repair Kit for Johnson/Evinrude V4 & V6 Crossflow Outboards The iFJF 18-7046 carburetor repair kit is specifically engineered for the V4 (85, 90, 100, 115, 140 HP) and V6 crossflow Johnson and Evinrude outboard engines. These legendary 2-stroke powerheads rely on precision carburetion for their signature performance — and this kit provides everything needed to restore each carburetor to factory specifications. Replaces OEM 439076 and covers V4 Crossflow and V6 Crossflow carbureted models. Key Features V4/V6 Crossflow Specific: Engineered for the high-performance carburetor design used on Johnson/Evinrude 85-140HP V4 and 150-235HP V6 crossflow engines. Complete Rebuild Kit: Float bowl gasket, inlet needle & seat, all body gaskets, mixture screw o-ring, welch plugs, and drain screw washers. High-Performance Fuel Systems: Precision needle & seat ensures consistent fuel level control at the high fuel flow rates demanded by V4 and V6 carburetors at WOT. Ethanol-Ready: Upgraded materials resist the ethanol-related degradation that plagues original 1980s-1990s rubber components. Restores Peak Power: Fixes lean conditions, fuel starvation, and uneven cylinder-to-cylinder fuel distribution that robs horsepower. Compatibility Engine Family HP Range Configuration Carb Count V4 Crossflow 85, 90, 100, 115, 140 HP V4 2-stroke 2 carburetors V6 Crossflow 150, 175, 200, 225, 235 HP V6 2-stroke 3 carburetors Cross-Reference / Interchange Brand Part Number Johnson / Evinrude OEM 439076 Sierra Marine 18-7046 GLM Marine 40570 Mallory Marine 9-37100 Installation Considerations for Crossflow Engines Carb synchronization is critical: After rebuilding all carburetors, adjust the throttle linkage so all throttle plates open simultaneously. Uneven opening causes cylinder-to-cylinder fuel imbalance. Check reed valves: While carbs are off, inspect the reed valves for chipping or fatigue. Damaged reeds cause spit-back and poor low-speed running. Verify timing: After carb rebuild, verify WOT timing with a timing light. Lean conditions from vacuum leaks can cause detonation at high RPM. Link and sync procedure: Follow the factory "link and sync" procedure for your specific model to set idle timing, pickup timing, and WOT timing correctly. Frequently Asked Questions Q: Will this fit my 1985 Johnson 115 HP V4?A: Yes, if your 115HP V4 uses the crossflow carburetor design (most 1980s models do). Verify your carburetor's OEM part number is 439076 or the equivalent crossflow carb series. Q: How many kits do I need for my V6 200 HP?A: V6 crossflow engines use 3 carburetors — you'll need 3 kits for a complete rebuild. Always rebuild all carburetors simultaneously for balanced performance. Q: Does this kit work for looper engines?A: No. This kit is for crossflow (deflector piston) engines only. Looper engines (60-degree V4 and V6 loop-charged models) use different carburetors. Verify your engine type before ordering. Q: What's the most common mistake during V4/V6 carb rebuild?A: Failing to properly synchronize the carburetors after installation. Even with perfectly rebuilt carbs, uneven throttle plate opening creates cylinder-to-cylinder imbalance. Always perform a link & sync procedure after rebuild. Q: My engine bogs when I hammer the throttle — will this fix it?A: Possibly. Bogging on acceleration is often caused by clogged high-speed jets or a failing accelerator pump circuit. The thorough cleaning during rebuild combined with new components addresses these issues. If bogging persists, check the accelerator pump diaphragm separately.

Apply vacuum with a hand pump. The secondary throttle shaft should move and hold position. If it doesn't hold vacuum, the diaphragm is torn. Frequently Asked Questions Q: How do I know if I need 135-4 vs 135-3?A: The 135-4 has a 2.054" rod length for universal Holley 4150/4160. The 135-3 has a shorter rod (Ford/Mopar OEM). Measure your existing rod. Q: Will this fit Quick Fuel SS-series carb?A: Yes. Quick Fuel vacuum secondary carbs use the same diaphragm assembly as Holley. Direct fit for HR, SS, and Slayer series. Q: Can I convert to mechanical secondary using this?A: This diaphragm is for vacuum secondary operation. To convert to mechanical, use this as a plug (block vacuum port) and install a mechanical secondary linkage kit (sold separately). Q: How long does installation take?A: 15-20 minutes. Remove the vacuum secondary housing cover (3 screws), swap the old diaphragm for new, replace the cork gasket. No carb removal required. Related ProductsBrowse more in our collection.

3-Pack Carburetor Rebuild Kit — Mercury/Mariner Outboard Motors The iFJF 18-7750-1 3-pack provides three complete rebuild kits in one value bundle — ideal for multi-carburetor outboard engines or marine repair shops. Each individual kit contains all gaskets, seals, inlet needle & seat, and o-rings required for a single carburetor overhaul. Replaces Mercury/Mariner OEM 1395-8236354, 1395-8236353, 1395-811222, 1395-9599, and Sierra Marine 18-7750-1. Key Features 3 Complete Kits: Each individually sealed and labeled — perfect for 3-cylinder outboards or stocking your repair bench. Bulk Value Pricing: Significant cost savings versus buying individual kits. Ideal for DIYers with multi-carb engines and professional marine mechanics. Ethanol-Resistant: All gaskets, o-rings, and seals formulated for modern E10 fuels — resists swelling, shrinkage, and deterioration. OEM-Spec Manufacturing: Precision-machined inlet needle & seat assemblies ensure consistent float height and leak-free fuel control. Multi-OEM Compatible: Replaces 1395-8236354, 1395-8236353, 1395-811222, 1395-9599, and Sierra 18-7750-1. Cross-Reference / Interchange Brand Part Number Sierra Marine 18-7750-1 Mercury OEM 1395-8236354, 1395-8236353 Mercury OEM (Alternate) 1395-811222, 1395-9599 Technical Specifications Quantity: 3 complete rebuild kits (each services 1 carburetor) Per-Kit Contents: Float bowl gasket, inlet needle & seat, body gaskets, o-rings, welch plugs, drain screw washers Material: Ethanol-resistant Buna-N / Nitrile, composite gasket Application: Select Mercury/Mariner 2-stroke outboard carburetors Storage: Keep in sealed package in cool, dry location until use Perfect for Multi-Carb Outboards Many 3-cylinder and V6 outboard engines use three or more carburetors. Rebuilding only one results in unbalanced fuel delivery — the rebuilt carb runs rich or lean compared to worn units, causing poor idle and uneven power. This 3-pack lets you overhaul all carburetors simultaneously, ensuring synchronized fuel delivery and smooth operation across the entire RPM range. Frequently Asked Questions Q: Does this 3-pack mean 3 sets of everything?A: Yes. You receive three individually packaged, complete rebuild kits — each containing all gaskets, seals, and needle valve components for one carburetor. Q: How many carbs does a typical Mercury 3-cylinder outboard have?A: Most 3-cylinder 2-stroke Mercury/Mariner outboards have 3 carburetors (one per cylinder). This 3-pack covers the entire engine in one purchase. Q: Are the kits individually sealed?A: Yes. Each of the 3 kits is separately packaged, so you can rebuild one carburetor at a time while keeping the remaining kits fresh and organized. Q: Does this fit V6 outboards with 3 carbs?A: If your V6 uses the same carburetor model as the 3-cylinder applications covered by this kit, then yes. Verify your carburetor model number before ordering. Q: What if I only need one kit?A: Single kits are available separately — search for our individual 18-7750-1 listing. The 3-pack is designed for multi-carb engines and professional users who want bulk value.

Carburetor Rebuild Kit for Mercury/Mariner 2-Stroke Outboard Motors The iFJF 18-7226 carburetor kit is a complete rebuild solution for select Mercury and Mariner 2-stroke outboard carburetors. This kit replaces critical wear components including gaskets, seals, inlet needle & seat, and bowl gasket — restoring proper fuel delivery and eliminating common issues like fuel leaks, hard starting, and poor idle quality. Designed to meet OEM specifications, each component is manufactured from ethanol-resistant materials for extended service life in modern fuel conditions. Key Features All-in-One Rebuild Kit: Contains every gasket, seal, o-ring, and needle valve required for a single carburetor rebuild — no need to source individual components. Ethanol-Ready Materials: Gaskets and seals resist swelling and deterioration caused by E10 and ethanol-blended marine fuels. Precision Manufactured: Float needle and seat are machined to exact tolerances for consistent fuel level control and leak-free operation. OEM Equivalent: Replaces Mercury/Mariner 35-16494-1, 35-816296-T1, 35-816296-1, 35-816296Q2, 35-816296T1, OMC 398327, and Sierra 18-7226. Common Fixes: Resolves fuel drip from carb throat, rough idle, bogging on acceleration, and hard hot re-starts. Cross-Reference Interchange Brand Part Number Sierra Marine 18-7226 Mercury / Mariner OEM 35-16494-1, 35-816296-T1, 35-816296-1, 35-816296Q2, 35-816296T1 OMC / Johnson Evinrude 398327 Mallory Marine 9-37404 Technical Specifications Application: Mercury / Mariner 2-stroke outboard carburetors Carburetor Type: Float bowl design (side bowl or center bowl applications) Kit Contents: Float bowl gasket, inlet needle & seat, body-to-adapter gasket, mixture screw o-ring, welch plugs, drain screw gasket Material: Ethanol-resistant Buna-N / Nitrile rubber, composite gasket material Fitment Type: Direct replacement Why Rebuild Instead of Replace? A complete carburetor assembly for a 2-stroke outboard can cost $200-400+. In most cases, the aluminum carburetor body itself is perfectly serviceable — only the soft components (gaskets, seals, needle valve) have degraded. The iFJF 18-7226 rebuild kit costs a fraction of a replacement carburetor and, when installed correctly, restores like-new performance. This is especially cost-effective for older engines where OEM carburetors may be discontinued or backordered. Installation Guide Remove carburetor: Disconnect fuel line, throttle linkage, and choke linkage. Remove mounting bolts/nuts. Disassemble completely: Remove float bowl, float pin, float, inlet needle, and all gaskets. Note the order of disassembly. Clean thoroughly: Soak all metal parts in carburetor cleaner. Use compressed air to blow through every passage and jet. Verify jets are clear. Install new components: Replace all old gaskets and seals with new kit components. Install new inlet needle & seat. Set float height: Verify float level matches specification. Adjust tab if needed. Reassemble and test: Reinstall carburetor, connect linkages and fuel line. Prime bulb, check for leaks before starting. Frequently Asked Questions Q: How do I confirm this kit fits my outboard?A: This kit is designed for Mercury/Mariner 2-stroke carburetors using OEM part numbers 35-16494-1 or 35-816296 series. Check the model number stamped on your carburetor body, or search your engine's serial number against the Sierra 18-7226 fitment guide. Contact us with your engine details if unsure. Q: Does this kit include a new float?A: No. The float is a separate component that typically only needs replacement if cracked or fuel-saturated. If your float is damaged, you'll need to source it separately. A simple test: shake the float — if you hear liquid inside, it needs replacement. Q: How many carburetors does one kit service?A: One kit services ONE carburetor. If your outboard has 2, 3, or 4 carburetors, you'll need multiple kits. We recommend rebuilding all carburetors simultaneously for balanced performance. Q: Will this fix my motor dying at idle?A: Possibly. Dying at idle is often caused by a clogged pilot/idle circuit or vacuum leak from a deteriorated gasket. A thorough cleaning during the rebuild combined with new gaskets resolves this in most cases. If the issue persists after rebuild, check for vacuum leaks at the intake manifold or crankshaft seals. Q: Can I use this kit with a carburetor that has been sitting with old fuel for years?A: Yes — and this is one of the most common use cases. Carburetors that have sat with ethanol fuel often have completely varnished internals. Follow the cleaning steps carefully, and consider an ultrasonic cleaning if the varnish is heavy. The new kit components will restore the sealing surfaces after cleaning.

Product Overview Unleash your V8's full potential with the iFJF 1407 4-Barrel Carburetor. This 750 CFM performance carburetor features a manual choke, square bore design, and mechanical secondaries — the go-to setup for street performance and weekend strip runs. The striking golden finish isn't just for looks — it's a corrosion-resistant coating that protects against ethanol-blended fuels. Whether you're building a crate motor, restoring a classic muscle car, or upgrading from a tired 2-barrel, the 1407 delivers crisp throttle response and reliable fuel delivery. Key Features 750 CFM Flow: Ideal for 350-454 cubic inch V8 engines — supports up to 500+ horsepower with the right cam and intake. Manual Choke: Simple, reliable cold-start enrichment — pull the cable, fire it up, push it in when warm. No vacuum diaphragm to fail. Square Bore Design: Compatible with most aftermarket intake manifolds (Edelbrock Performer, Weiand, Holley pattern). Mechanical Secondaries: Instant throttle response — secondaries open with your right foot, not engine vacuum. Perfect for aggressive driving. Golden Dichromate Finish: Corrosion-resistant coating protects against modern ethanol-blended fuels and looks great under the hood. Air Valve Secondary: Adjustable secondary air valve tunes the transition from primary to WOT — eliminates the bog common with vacuum secondary carbs. Recommended Applications Engine Size Cam Type Usage 350-383 CID Mild to Hot Street Street / Weekend Strip 400-454 CID Stock to Mild Street Cruiser / Towing 383-454 CID Hot Street / Race Strip / Performance Street Specifications Spec Detail Model 1407 CFM Rating 750 Barrels 4 Choke Manual Bore Type Square Bore Secondaries Mechanical with Adjustable Air Valve Finish Golden Dichromate Fuel Inlet Single (3/8" NPT) Tuning Tips Set Float Levels: Adjust to the middle of the sight glass window with the engine running — too high causes rich idle, too low causes lean stumble. Idle Mixture: Start at 1.5 turns out. Adjust for highest vacuum reading, then back each screw out 1/8 turn for a slightly rich idle — smoother transition off-idle. Secondary Air Valve: Adjust the spring tension to open secondaries without bogging. Too loose = bog; too tight = secondaries never open. Start with 3/4 turn of preload. Fuel Pressure: Keep fuel pressure between 5-7 psi. Above 7 psi can overwhelm the needle and seat, causing flooding. Frequently Asked Questions Q: Will this carburetor fit my intake manifold?A: The 1407 has a square bore bolt pattern compatible with most aftermarket 4-barrel intake manifolds (Edelbrock, Weiand, Holley-square-bore). It will NOT fit a spread-bore manifold (Quadrajet pattern) without an adapter plate. Q: Is 750 CFM too much for my 350?A: A 750 CFM carb works well on a 350 with a performance cam, headers, and intake. For a bone-stock 350 with stock heads and cam, a 600-650 CFM carb would be better matched. The 1407's air valve secondaries help prevent over-carburetion by only flowing what the engine demands. Q: How is the manual choke set up?A: You'll need a manual choke cable kit (sold separately) routed to the cabin. Mount the cable under the dash, connect it to the carb's choke lever, and adjust for full open/close travel. Many hot-rodders prefer manual chokes for their simplicity and reliability. Q: Does this carb support a kickdown linkage?A: Yes — the throttle lever includes provisions for GM TH350/TH400, Ford C4/C6, and Chrysler 727 kickdown linkages. An aftermarket bracket may be needed for some applications. Q: Is this ready to run out of the box?A: The 1407 comes pre-calibrated for a typical performance V8. You'll need to set the idle speed, idle mixture, and float levels. The secondary air valve may need adjustment based on your specific engine combination.

No hunting for missing pieces Ethanol-resistant materials — Modern gaskets and diaphragms handle E10 fuel without swelling Precision fit — Manufactured to exact Keihin CDK-2 specifications Restores performance — Proper fuel metering = crisp throttle response and reliable starting Cost-effective — Far cheaper than replacing carbs or buying OEM parts individually Frequently Asked Questions Q: Does this kit cover both carbs?A: Yes — this is a complete twin carburetor kit. It includes enough gaskets, diaphragms, needles, and seals to fully rebuild both the front and rear carburetors. Q: Will this fit my 1996 Kawasaki 750 ZXI?A: Yes. The kit covers all 750 ZXI models from 1995-1997 with Keihin CDK-2 twin carburetors. Q: Do I need any special tools for this rebuild?A: Basic metric wrenches, screwdrivers, and carb cleaner are all you need. A pop-off pressure tester is recommended (but not required) for setting needle seat pop-off pressure correctly. Q: Are these ethanol-safe?A: Yes. The gaskets and diaphragms are manufactured from modern fuel-resistant materials that won't swell or degrade with E10 (10% ethanol) fuel. We still recommend draining carbs for long-term storage. Q: My ski sat for 2 years — will this kit fix it?A: If the engine has compression and spark, a carb rebuild is the #1 fix for skis that have been sitting. Old fuel turns to varnish and clogs the tiny passages inside Keihin carbs. A thorough cleaning plus this rebuild kit usually gets them running again.
