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.

Product Overview Unlock the hidden potential of your Jeep's legendary 4.0L inline-6 with the iFJF 62mm High-Flow Throttle Body. The factory throttle body on 1991-2006 4.0L engines uses a restrictive 55-58mm bore that chokes airflow above 3,500 RPM — right where you need power for highway passing, towing, and steep grades. Our 62mm CNC-machined throttle body increases airflow by 15-20%, delivering 10-15 additional horsepower and noticeably sharper throttle response. Precision-machined from billet aluminum with a tapered bore, it's a direct bolt-on that works with your factory sensors, intake, and ECU — no tuning required. Key Features 62mm High-Flow Bore — Increases intake airflow by 15-20% over stock 55-58mm. Tapered entry smooths airflow for better cylinder filling across the RPM range. CNC Billet Aluminum Construction — Precision-machined from solid 6061-T6 billet. Far more durable than cast OEM throttle bodies prone to vacuum leaks around shaft bushings. 10-15 HP Gain — 8-12 HP on stock engine, 12-15 HP paired with cold air intake and cat-back exhaust. Gains most noticeable 2,500 RPM to redline. Improved Throttle Response — Larger bore means less restriction at partial throttle. Feel the difference in tip-in response and mid-range passing power immediately. Direct Bolt-On, No Tuning — Uses factory IAC valve, TPS sensor, and throttle cable. Stock ECU adapts fuel trims automatically. ~45 minute install.

Remove intake tube from throttle body. Disconnect IAC and TPS electrical connectors. Remove 4 throttle body mounting bolts (10mm). Remove throttle cable bracket. Transfer IAC valve and TPS sensor from old throttle body to new one. Use new gasket (included). Install new throttle body with supplied bolts. Torque to 12 ft-lbs in cross pattern. Reconnect intake tube, connectors, and throttle cable. Verify smooth throttle plate movement. Reconnect battery. Start engine and idle 5 minutes — ECU auto-learns new idle parameters. Frequently Asked Questions Q: Will this cause a Check Engine Light?A: No. The 62mm bore is well within the ECU's adaptive fuel trim range. Factory computer automatically adjusts idle air control and fuel mapping. No CEL, no tune required. Q: Do I need a cold air intake to see gains?A: You'll see 8-10 HP with the stock airbox. Pairing with a CAI maximizes the benefit — CAI removes upstream restriction, 62mm TB removes downstream restriction. Q: Will this hurt fuel economy?A: At cruise (light throttle), the larger bore doesn't affect consumption. Under acceleration, you'll use slightly more fuel making more power. Most report 0-1 MPG change in mixed driving. Q: Too big for a stock 4.0L?A: 62mm is the sweet spot. Larger bores (64mm+) cause part-throttle drivability issues and reduce low-end torque. 62mm provides best airflow/velocity balance. Q: Fits the 2.5L 4-cylinder?A: No — 4.0L inline-6 only. The 2.5L uses a different bolt pattern and would be over-bored at 62mm. Q: Boring stock TB vs this billet TB?A: Boring removes material but can't fix worn throttle shaft bushings (common vacuum leak source on high-mileage 4.0Ls). Our billet TB starts fresh with precision bearing surfaces and tapered entry bore.

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.

1478 Electric Choke Conversion Kit for Edelbrock 1405/1406 Carburetors The iFJF 1478 Electric Choke Kit converts your manual-choke Edelbrock 1405 (or replaces a worn electric choke on the 1406) to automatic 12V electric choke operation. No more fishing a choke cable through the firewall — just pump the gas once, turn the key, and the thermostatic choke element handles cold-start enrichment automatically. Key Features Direct Fit — Bolt-on replacement for Edelbrock 1405 and 1406 Performer Series carburetors 12V Electric Operation — Connect to any ignition-switched 12V source for automatic choke function Thermostatic Element — Bimetallic spring opens the choke plate progressively as the engine warms up Includes All Hardware — Choke housing, thermostatic element, fast idle cam, linkage, screws, and gasket Adjustable — Rotate the housing to fine-tune choke opening rate for your climate and engine setup Vacuum Pull-Off Compatible — Works with the existing internal vacuum piston on your 1405/1406 Compatibility Carburetor Model Application 1405 Performer (Manual Choke) Converts manual to electric choke 1406 Performer (Electric Choke) Replacement for worn/failed electric choke Installation Overview Remove the manual choke housing (3 screws) from the passenger side of the carburetor Install the new choke housing with the provided gasket Connect the fast idle linkage to the choke shaft Route the 12V wire to an ignition-switched power source Adjust the choke housing index to set the correct opening rate Frequently Asked Questions Q: Will this fit my 1405 carburetor? A: Yes — the 1478 kit is specifically designed as a direct bolt-on conversion for the Edelbrock 1405 manual choke carburetor. It also fits the 1406 as a replacement electric choke unit. Q: Where should I connect the 12V wire? A: Connect to a key-on 12V source such as the ignition coil positive terminal, the IGN terminal on the fuse box, or a switched 12V circuit. Do not connect to constant 12V — the choke element will drain the battery when the engine is off. Q: How do I adjust the choke? A: The choke housing has index marks. Rotate clockwise (richer) for colder climates or engines that need more warm-up enrichment. Rotate counter-clockwise (leaner) for warm climates. The factory setting (center mark) works well for most applications in temperate regions. Q: Do I need to re-jet after installing the electric choke? A: No. The choke only affects cold-start and warm-up enrichment. Once the engine reaches operating temperature, the choke is fully open and has zero effect on the main fuel circuit. Q: Can I install this without removing the carburetor? A: Yes — the choke housing is accessible on the passenger side of the carburetor and can be swapped with the carburetor installed on the engine. The job typically takes 15-30 minutes. 🔗 Related Products from iFJF 1405 Performer 600 CFM Carburetor 1406 Performer 600 CFM Carburetor 📚 Helpful Installation Guides 📖 Diesel Engine Cooling System Flush Guide 📖 GM Truck Tie Rod Upgrade Installation

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.

PZ20 Aluminum Alloy Carburetor for 50cc-125cc ATVs & Dirt Bikes The PZ20 Carburetor is a performance-grade replacement built from ATC12 aluminum alloy, designed for 50cc, 70cc, 90cc, 110cc, and 125cc Chinese ATVs and dirt bikes. Precision-machined internal passages deliver consistent air-fuel mixture across the RPM range, eliminating the bogging, hard starting, and erratic idle common with worn or corroded stock carburetors. Compatible Models Brand Compatible Models TaoTao ATA-50, ATA-70, ATA-90, ATA-110, Cheetah, New Cheetah Kazuma Meerkat 50, Falcon 90, Viper 110 SunL SLA-50, SLA-70, SLA-90, SLA-110 Baja DR50, DR70, DR90, Wilderness 90 NST 50cc, 70cc, 90cc, 110cc ATVs Other Any Chinese 50cc-125cc with PZ20 flange pattern Key Features ATC12 Aluminum Alloy Construction — Superior to pot metal OEM carburetors; resists oxidation, corrosion, and ethanol fuel degradation over years of use Precision Machined Internals — CNC-machined jets, needle, and emulsion tube ensure smooth throttle response from idle to WOT Direct Bolt-On Replacement — Same PZ20 flange pattern and throttle cable fitting as OEM; swap in 15 minutes Adjustable Idle & Air-Fuel Mixture — Fine-tune idle speed and mixture screw for your specific altitude and modifications Complete Assembly — Includes carburetor, gaskets, fuel line, and intake manifold boot Increased Airflow — Slightly larger venturi than budget stock units for better top-end performance Technical Specifications Specification Value Carburetor Type PZ20 (20mm Venturi) Material ATC12 Aluminum Alloy Engine Size 50cc-125cc (4-Stroke) Mounting 2-Bolt Flange (Standard PZ20 Pattern) Choke Manual Lever Fuel Inlet Single Barb (3/16" line) Installation Guide Remove the old carburetor, intake manifold, and gaskets Clean the intake mounting surface thoroughly — old gasket residue causes air leaks Install the new intake boot and gasket, then mount the PZ20 Connect the throttle cable and adjust for 1-2mm of free play Attach the fuel line — use an inline fuel filter (recommended) Set the idle mixture screw 1.5 turns out from fully seated as a starting point Start the engine, warm up, and fine-tune the idle speed and mixture FAQ Q: Will this fit my brand 110cc ATV?A: If your ATV uses a PZ20 carburetor with the standard 2-bolt flange pattern and a manual choke lever, this fits. The PZ20 is the most common carburetor on 50cc-125cc Chinese ATVs from TaoTao, Kazuma, SunL, Baja, NST, and similar brands. Q: Do I need to re-jet after installing?A: The PZ20 comes pre-jetted for the 50cc-125cc range. Most users can bolt on and ride. If you have an aftermarket exhaust, intake, or ride at high altitude, you may need to adjust the needle clip position or change main jet size. Q: How is this better than the stock carburetor?A: OEM carburetors on budget ATVs use low-grade pot metal that corrodes, especially with ethanol fuel. The ATC12 aluminum alloy resists ethanol corrosion, maintains cleaner internal passages, and delivers more consistent performance. Q: What is included in the kit?A: PZ20 carburetor, intake manifold boot, gaskets, fuel line, fuel filter, hose clamps, and mounting hardware. Q: My ATV has been sitting — will this fix the no-start issue?A: If the old carburetor is gummed up from stale fuel, a new PZ20 will solve the problem. We also recommend draining old fuel, flushing the tank with fresh gas, and replacing the fuel filter at the same time.

If you have modified your engine (exhaust, intake, cam) or ride at high altitude (5,000+ feet), re-jetting may be needed.

iFJF 845273 Replacement Carburetor — Briggs & Stratton 611477 / 613477 Series The iFJF 845273 is a complete replacement carburetor for Briggs & Stratton 611477 and 613477 series engines found on lawn mowers, pressure washers, tillers, and other outdoor power equipment. If your engine surges, stalls under load, or refuses to start despite fresh fuel and a clean spark plug, a worn carburetor is the likely culprit. Our direct-fit replacement bolts on in minutes and comes pre-adjusted for reliable operation right out of the box. Key Features & Benefits OEM-Spec Replacement Engineered to match B&S part numbers 845273, 842097, 844172, and 845032. The throttle and choke linkage mounting points, fuel inlet position, and mounting bolt pattern are identical to the OEM carburetor — no modifications, no adapter plates, no frustration. Complete Kit — Carburetor + Fuel Filter + Gaskets Includes the carburetor, mounting gaskets, and an inline fuel filter. The filter catches debris before it reaches your new carburetor, protecting your investment from the first start. Everything arrives in one box. Pre-Adjusted Fuel Mixture Factory-set for the correct air-fuel ratio on B&S 611477 and 613477 engines. Minor idle-speed adjustment may be needed for your specific application, but you won't need to mess with the mixture screws. Technical Specifications Specification Detail Model iFJF 845273 Replaces OEM B&S 845273, 842097, 844172, 845032 Engine Series B&S 611477, 613477 Included Carburetor, Gaskets, Fuel Filter Fuel Type Gasoline Common Applications Briggs & Stratton 611477 Series Walk-Behind Mowers B&S 613477 Series Self-Propelled Mowers Pressure Washers (B&S powered) Rotary Tillers & Cultivators Generators with B&S 550-650 Series Engines Lawn Edgers & Leaf Blowers Installation Disconnect spark plug wire. Turn fuel valve OFF or clamp the fuel line. Remove the air filter housing. Disconnect the throttle linkage and governor spring. Remove mounting bolts and lift off old carburetor. Clean the mounting surface. Install new carburetor with gaskets. Tighten bolts evenly. Reconnect linkages and install the inline fuel filter (arrow pointing toward carburetor). Restore fuel, reconnect spark plug, and start. Let warm up and adjust idle if needed. Frequently Asked Questions How do I know if my engine is a 611477 or 613477 series? The engine model number is stamped on the metal blower housing or valve cover. Look for a string like "12H802" or "126M02" — the first two digits indicate cubic inches (12), and the "H8" or "M0" prefix helps identify the series. You can also search your engine's full model number on the Briggs & Stratton website to confirm series compatibility. Does this carburetor come with a new primer bulb? The primer bulb is typically part of the air filter housing, not the carburetor itself. If your primer bulb is cracked or not working, it may need to be replaced separately. The carburetor does include the primer port for connection. Can I use this on a Craftsman mower? Yes, if your Craftsman mower has a B&S 611477 or 613477 series engine. Many Craftsman, Husqvarna, and MTD mowers use these engines. Always verify the engine model number rather than the mower brand/model. Will a new carburetor fix hard starting? In most cases, yes — if the hard starting is caused by a clogged or worn carburetor. If hard starting persists after replacement, check the spark plug, ignition coil, and valve clearances. Fresh fuel and a clean air filter also help significantly. Related Products iFJF 799727 Carburetor B&S Intek 14-18HP iFJF 796184 Carburetor Rebuild Kit + Air Filter iFJF 699915 Fuel Solenoid Valve
