Carburetor Overhaul Kits. Fits Carter and Kohler carburetors used on Kohler K-series and early Magnum single and opposed twin cylinder engines, and various other makes and models of small engines. Includes: 3/8" brass fuel inlet seat w/gasket, Viton-tip fuel inlet float valve, alcohol-resistant neoprene rubber float bowl O-ring seal, alcohol-resistant neoprene rubber fuel baffle/splash shield, fiber bottom float bowl gasket and float hinge pin. NOTE: High quality aftermarket kits are equal to or surpasses the quality of the OEM Kohler overhaul kit. IMPORTANT: Before reinstalling a used float bowl on the carburetor, place it on a hard, flat surface, and flatten the bottom of the bowl from the inside with a small hammer. When the bowl is installed on the carburetor body with the retaining bolt tightened, this will "clamp" or squeeze the fuel baffle/splash shield against the O-ring to prevent splashing fuel from seeping out around the top of the float bowl when the engine is in operation.

Also fits Tecumseh engines with the Carter or Walbro carburetors with the large bowl, and Briggs and Stratton 7hp-12hp vertical shaft flathead engine carburetors. (FYI - The early Briggs & Stratton float carburetors was designed and made by the Carter Carburetor Corporation.) Dimensions (±): 2-3/16" I.D. x 2-7/16" O.D. x .040" thickness. Alcohol-resistant neoprene rubber O-ring included in overhaul/rebuild kits listed above. IMPORTANT: Before reinstalling a used float bowl on the carburetor, place it on a hard, flat surface, and flatten the bottom of the bowl from the inside with a small hammer. When the bowl is installed on the carburetor body with the retaining bolt tightened, this will "clamp" or squeeze the fuel baffle/splash shield against the O-ring to prevent splashing fuel from seeping out around the top of the float bowl when the engine is in operation.

Alcohol-Resistant Neoprene Rubber Fuel Baffle/Splash Shields. This particular part prevents splashing fuel inside the float bowl from traveling up through the atmospheric vent passageway and possibly being sucked into the throttle bore, which can momentarily cause engine misfire due to normal or high RPM engine vibrations. Fastens between bowl O-ring seal and float bowl. Required in all carburetors. Fits all Carter Model N #13, #16, #18, #20, #22 and Carter or Kohler #26, #28, #30 carburetors used on the Kohler K-series and early Magnum single cylinder 4hp-16hp, 18hp OHV single- and twin-cylinder flathead cast iron block engines. Included in overhaul/rebuild kit listed above. IMPORTANT: Before reinstalling a used float bowl on the carburetor, place it on a hard, flat surface, and flatten the bottom of the bowl from the inside with a small hammer. When the bowl is installed on the carburetor body with the retaining bolt tightened, this will "clamp" or squeeze the fuel baffle/splash shield against the O-ring to prevent splashing fuel from seeping out around the top of the float bowl when the engine is in operation.

Brass Float. Fits all Carter Model N #13, #16, #18, #20, #22, and Carter or Kohler #26, #28, #30 carburetors used on the Kohler K-series, early Magnum single cylinder K90-K361 single- and twin-cylinder flathead cast iron block engines. May also fit certain carburetors used on Onan engines. Replaces the very early obsolete tapered/inverted cone-shape brass float in the Carter Model N #13 carburetor used on the Kohler K90 and various other makes and models of small engines. Dimensions (±): 15/16" I.D. x 1-15/16" O.D. x 5/8" tall. NOTE: The float level/height must be set correctly on ALL brass floats when installed. They do not come preset. The correct way to set the float level is remove the carburetor from the engine, remove the float bowl, and with the carburetor upside-down, use a small flat blade screwdriver to bend the tab on the float slightly one way or the other to set the float parallel with the carburetor body. Make sure the float moves up and down freely, too. If it binds or sticks, carefully use a flat file to narrow the sides of the hinge for clearance. Be careful not to file into the float itself!
  • High quality aftermarket. Replaces discontinued Kohler part # 25 757 03-S. $10.00 each, plus shipping & handling.
Float Stabilizer Spring. Fits Carter Model N #13, #16, #18, #20, #22, and Carter or Kohler #26, #28, #30 carburetors. Minimizes float bounce due to normal competition pulling engine vibration at open RPM/wide open throttle operation, or excessive small all terrain vehicle "bouncing around" over rough and uneven terrain, which could cause momentary engine misfire and/or fuel spillage out of the atmospheric vent opening (air passageway from inside the float bowl area to outside of carburetor). Not necessary for 4,000± RPM competition pulling engines or ordinary general lawn and garden equipment.
  • Used and in excellent condition. $7.00 each, plus shipping & handling. (When available or in stock)
  • New. OEM Kohler part # 237917-S. $14.30 each, plus shipping & handling.

Dimensions of each float bowl: 2-3/8" O.D. x 1-1/4" height x 3/8" bottom hole.

May also fit Walbro carburetors used on certain Onan engines. All rubber-like parts made of alcohol-resistant neoprene. Includes carburetor mounting gasket. NOTE: On all Walbro WHL and WHG carburetors, the fuel inlet seat is pressed-in at the factory. If it's replaced with a new seat, fuel will likely leak around the edge of the seat and overflow the float bowl, rendering the carburetor body useless. So it'll be best to just install a new fuel inlet valve and leave the OEM seat intact. Remember - In the laws of physics, the moving part will likely to wear more than the stationary part.
  • OEM Walbro part # K1-WHG. Replaces Tecumseh part # 632445. $13.00 each, plus shipping & handling.

May also fit Walbro carburetors used on certain Onan engines. NOTE: On all Walbro WHL #36, #44 and WHG #52, #60, #64 carburetors, the fuel inlet seat is pressed-in at the factory. If it's removed and replaced with a new one, the carburetor body may be rendered useless, because it will mostly likely leak fuel. So it'll be best to just install a new fuel inlet valve and leave the seat alone. Remember - in the laws of physics, the moving part will wear more than the stationary part. Not available separately from Kohler. OEM Walbro part # 82-529-7. $7.00 each, plus shipping & handling.

Convert the Carter or Kohler #26, #28 or #30 Carburetor to a Bottom Main Fuel Adjuster - [Top of Page]

The bottom high speed main fuel adjuster assembly has 3/8" fine threads, and is not an OEM Kohler part and is not a modification by Kohler. The conversion provides no high performance engine enhancements whatsoever, but it is an absolute must for an open RPM competition pulling engine. It's an add-on feature that replaces the OEM float bowl retaining bolt listed above only to prevent wearing of and enlarging the fuel main jet hole by the end of the OEM high speed needle air/fuel adjustment screw due to normal engine vibration at open RPM engine operation. This conversion have been proven many times to function flawlessly for a 4,000 RPM stock competition pulling engine and for an open RPM competition pulling engine! Read below how to convert a Carter or Kohler carburetor for use with the bottom adjuster.

Actually, the same bottom fuel adjuster design that's mentioned here was first used on Briggs & Stratton's 6-12.5hp vertical shaft flathead engine carburetors, which was designed and made by the Carter Carburetor Corporation, and it works excellent! The B&S bottom adjuster has 5/16" fine threads and will not fit the Carter or Kohler #26, #28 or #30 carburetors, but will fit the Carter Model N #13, #16, #18, #20, #22 carburetors when these carburetors is converted for use with the bottom adjuster.

  • Bottom Main Fuel Adjuster with Nylon Spacer Kit. Fits all Carter or Kohler #26, #28 and #30 carburetors used on Kohler K-series and early Magnum engine models K241, M10, K301, M12, K321, M14, K341, M16 and K361. Can also be used in the carburetor on all Briggs & Stratton opposed twin cylinder flathead engines to "fine tune" the high speed air/fuel mixture. NOTICE: Being I have no idea how long the bottom adjusters that I order from our suppliers been sitting on their shelf, the original rubber O-ring may or may not be deteriorated, cracked and dry-rotted. The new bottom adjuster can be used the way it is, but if it leaks fuel, it will need a new rubber O-ring installed. Make sure the compression nut is snug against the O-ring too, to prevent a fuel leak and to prevent the adjuster valve from rotating outward on its own from normal engine vibrations. $25.00 per kit, plus shipping & handling.

How to Convert a Carter or Kohler #26, #28 or #30 Carburetor for use with the Bottom Main Fuel Adjuster - This simple and easy to do design is a proven, ingenious and innovative concept by Brian Miller, because nobody else advertise this type of simple, low cost foolproof conversion.

  1. Use pliers to break off the tip of the OEM high speed [long needle] main fuel top adjuster at the lower idle fuel feed hole (orifice). (It's just soft brass.) Doing this turns the high speed adjuster into just an idle fuel vacuum tube. Preferably use an adjuster with a damaged tip for this conversion. There's no need to ruin a good adjuster for this.
  2. Grind to a dull point/bevel the end of the stem/tube so fuel can flow around it smoothly at high RPM without disruption.
  3. Use a carburetor jet cleaner wire set or an oxy-acetylene welding torch tip cleaner of the correct size, and then use 150± P.S.I. air pressure to clear out any remaining dried gas or debris to allow fuel to be drawn through the tube so the engine will idle.
  4. Replace the OEM compression spring [on the top adjuster] with a 1/4" I.D. x 1/4" length aluminum, nylon or steel spacer, or a stack of small O.D. washers measuring 1/4" I.D. x 1/4" in height. NOTE: The 1/4" height spacer/washers positions the very end of the stem/tube approximately midway in the float bowl and about 3/16" above the main jet hole so fuel can be drawn through the stem/tube for the engine to idle. If the end of the stem/tube is installed too low, it may make contact with the bottom adjuster, or if it's installed too high, the engine may not idle.
  5. Reinstall the top adjuster in the carburetor body with the spacer or washers and tighten it in place, making it fixed and non-adjustable. Making the top adjuster adjustable with the spring at this point will serve no purpose whatsoever.
  6. Reinstall the float, bowl, etc. in reverse order of removal, and install the bottom adjuster instead of the OEM float bowl retaining bolt, and tighten the bottom adjuster with a new sealing washer. IMPORTANT - Do not overtighten the bottom adjuster! This could strip out the threads in the carburetor body, which would render it totally useless.
  7. Install the carburetor on the engine, linkages, fuel hose, and start the engine.
  8. Adjust the idle air/fuel mixture screw and the high speed air/fuel mixture bottom adjustment screw until the engine idles smoothly and revs to full throttle without running lean or too rich on fuel.

FYI - Absolutely nothing needs to be done to the idle fuel passageway or the idle air/fuel mixture adjustment screw. Just leave them as-is, or use 150± P.S.I. compressed air to clear out the idle fuel passageway if necessary. The engine should idle fine after this conversion is performed. And there's definitely no need to install a small brass tube next to the float going directly up to the idle air/fuel mixture adjustment screw. Doing this could cause the brass tube to interfere with the operation of the float at high RPM. Also, if you're wondering if the presence of the top fuel adjuster stem/tube in a bored-out "straight through" throttle bore will slow down the incoming airflow, well, the throttle plate and throttle shaft are about 30% wider than the diameter of the top adjuster stem/tube, even with the throttle shaft ground/milled narrow or made thin to allow for more airflow through the carburetor.

  • New. This part is professionally CNC machined and not available from Kohler. Irrelevant OEM Kohler part number. $20.00 each, plus shipping & handling. (When available or in stock.)

NOTE: When rebuilding a plain, stock Carter or Kohler carburetor, in most cases, there's no need to remove the main jet/nozzle. If it won't come out, then don't worry about it. All that has to be done to make sure the bottom hole (jet) and the emulsion/side holes are open and clear of debris. To check if the emulsion/side holes are open, simply spray WD-40 or carburetor cleaner (in an aerosol can) through the small hole just under the choke plate and observe if the spray exits out the main nozzle in the throttle bore and out the jet in the bottom of the carburetor. But if the screwdriver slot in the main jet/nozzle is slightly stripped and it was able to be removed, for easier reinstallation, with the main jet/nozzle gently clamped in a bench vise, use a hacksaw blade to cut a slightly deeper screwdriver slot in the main jet/nozzle. And if modifying a carburetor to bore the venturi, the main jet/nozzle must be removed. Click here to learn how to remove the main jet/nozzle.

Kohler Anti-Backfire/Engine Shut-Off Solenoid Valve Kit. This anti-backfire solenoid valve fits in the carburetor and shuts off the engine when the ignition is turned off. The solenoid is energized the entire time the ignition switch is turned on to allow incoming air in the float bowl so the engine will run. When the ignition is turned off, it blocks off the incoming air in the float bowl to create a vacuum in the float bowl to prevent fuel from entering the combustion chamber, so the engine eventually shuts down. And with no raw fuel in the hot muffler, there is no possibility of a backfire. When the solenoid fails to function, the engine will not start. This particular part is designed for Kohler engine models K181 with specification numbers 13802, 13803, 13804, 13805, 13806, 13807, 13808, 13809, 13810, 13811, 13812, 13813, 13814, 13815, 13816, 13817, 13818, 13820, 30671, 30715, 30739; M18 with specification numbers 24610, 24637, 24652; M20 with specification numbers 49547, 49564, 49605; K582 with specification numbers 36246, 36249, 36261, 36266, 36268, 36285, 36310, 36327, 36337, 36350, 36371, 36373, 36374, 36376, 36382, 36392, 24600, 24603. OEM Kohler part # 25 755 05-S. $101.45 each, plus shipping & handling.

NOTE: Being the solenoid (OEM Kohler part # 25 755 06-S) for Kohler engine models M18 with specification numbers: 24563, 24568, 24574, 24577, 24592, 24594, 24599, 24619, 24630, 24631, 24636, 24646, 24655, 24656, 24659, 24664, 24674, 24696, 49514, 49544, 49545, 49565, 49569, 49570, 49572; M20 with specification numbers: 49584, 49595, 49599, 49608, 49623, 49624, 49629; MV20 with specification numbers: 57501-57514, 57527, 57528 is no longer available, to convert these engines without use of the solenoid, remove the failed solenoid and valve, cut short 3/8" threads in the hole (remove the float bowl first and use compressed air to clear out the metal cuttings afterwards), and install a short 3/8" Allen set screw in the hole. Don't thread the set screw deep into the hole, or it will block off outside atmospheric air from entering the float bowl. Without a solenoid and with the conversion, the engine will require a different ignition switch to shut off the spark. And the engine should be idled down before shutting it off to lessen the chance of a backfire out the muffler.

High Speed Air/Fuel Mixture Needle Adjustment Screws for Carter Model N #13, #16, #18, #20, #22 Carburetors. NOTE: Various high speed air/fuel adjustment screws are designed for a particular carburetor. The part number of the carburetor to match the type of adjuster are listed below. Kohler don't give their dealers much information on this. When compared the type of adjuster to the part numbers on each carburetor, A-1 Miller's found that some are in fact different. The tiny holes midway on the stem of the high speed adjuster allows a small amount of air to be mixed with fuel through the idle circuit so the engine won't idle too rich or too lean on fuel. And with no tiny holes present midway allows full flow of fuel through the idle circuit, which when used in a wrong carburetor, may cause the engine to idle too rich on fuel. So if an engine idles well (with the present adjuster), then the carburetor has the correct adjuster. Also, being the high speed adjusters are made of soft brass, if the pointed tip is slightly bent, it can be easily straightened with pliers and reused, and should not effect engine performance whatsoever. It's a valve that regulates the amount of fuel that goes in the engine. The tip does not need to be centered with the hole in the main jet/nozzle (emulsion tube). Gas will still get around it. And over-tightening the needle in the main jet hole will crush the tip out of shape, making it difficult to regulate the fuel. If the tips is damaged from being overtightened, the high speed adjuster will need to be replaced.

A worn/loose throttle shaft is the #1 cause of most engines wearing out and burning/consuming [crankcase] oil prematurely, and this is also what could cause the [high dollar] cylinder head to overheat and crack on a flathead engine. If a carburetor has a worn throttle shaft, this will create a vacuum leak through the throttle shaft and carburetor body, and the engine will idle poorly, if at all at times. With a worn throttle shaft, the engine will draw in dusty and dirty outside air (through the throttle shaft and carburetor body), which will cause increased wear to the throttle shaft and possibly carburetor body, intake valve face/seat and score the cylinder wall, and engine will eventually burn oil, blow blue/gray smoke out the exhaust, be hard to start and it will lose power. More than .010" of free-play/looseness is considered too much for throttle shaft wear. Although the throttle shaft can be moved and checked by hand, the most accurate way to check for the amount of wear is with a dial indicator. Plus, at normal governed operating speed (3,600 RPM), the extra incoming air will cause the engine to run lean on fuel (lean out the air/fuel mixture), which will overheat the combustion chamber and cause the cylinder head to warp and possibly burn-out, resulting in a blown head gasket. Plus, the piston and rings will also wear prematurely, eventually resulting in severe engine wear, excessive oil burning, engine smoking and loss of power.

FYI - All Carter or Kohler and Walbro carburetors didn't come with a throttle shaft bushing installed by the factory. A new bushing (and [oiled] foam rubber seal; listed below) must be installed when the throttle shaft is worn/loose in the carburetor body, or if the throttle shaft is severely worn thin, a new bushing along with a new throttle shaft (and foam rubber seal) must be installed. The oil on the foam rubber seal traps and blocks any dust and dirt from entering past the bushing and throttle shaft. If there's a counterbore (recession in the carburetor body) where the throttle shaft is, a short, flat bronze bushing can be installed, and if the original throttle shaft isn't worn much, it can be reused. But if there's no counterbore, the carburetor body will need to be precision aligned-bored for installation of a bronze sleeve bushing, and chances are, a new throttle shaft will also need to be installed. Precise machining of the carburetor body is required for installation of the sleeve bushing. And aLL Carter and Kohler #26, #28 and #30, and the older Walbro WHG #52, #60 and #64 carburetors have the counterbore. Only the newer Walbro WHG #52, #60, #64, and the aftermarket carburetors don't have the counterbore. If the carburetor has the counterbore, the throttle shaft will need to be removed, the dirt and debris will need to be cleaned out from the counterbore, and then the short, flat bushing can be installed. The [oiled] foam rubber seal will need to be installed on the throttle shaft before installing in the carburetor body. But if there's no counterbore, the upper hole in the carburetor body will need to be bored out in precision alignment with the lower hole in a milling machine, and then a bronze sleeve bushing can be installed. Along with regular maintenance, proper repair of a worn throttle shaft is required to help an engine last a long time.

Furthermore, the lower hole for the throttle shaft in the carburetor body rarely wears because most of the pressure is on the upper part of the shaft. If the bottom part of the throttle shaft itself is worn, a new throttle shaft will need to be installed. To find if the lower hole is worn, remove the throttle shaft, and insert a rod that measures exactly 1/4" into the hole and try to wiggle it around. If it doesn't wiggle, then the throttle shaft is worn. But if it does wiggle, then I don't have a fix to repair the lower throttle shaft hole. You will need to acquire another carburetor body or a complete carburetor (that matches yours) in good condition. I have new throttle shafts in stock and used carburetor bodies in good condition.

Installation Instructions for Throttle Shaft Bushing Above: On all Carter, Kohler and certain Walbro carburetors, the throttle shaft is not worn 1/8" below the lever. The bushing makes contact with this area to give the shaft a second life. All older Kohler throttle shafts are like this. (Kohler was thinking ahead with this design.) The original throttle shaft can be reused with this bushing if it isn't severely worn or damaged. Before removing the throttle plate retaining screws, and to avoid breaking off the soft OEM brass throttle (or choke) plate retaining screws, use a Dremel or equivalent small rotary grinder chucked with either an 1/8" high speed steel end mill or a chainsaw sharpening stone to grind away the flared threaded end of the screws, then the screws can be easily removed without breaking off. But if you didn't read this information beforehand, and the screw(s) broke off, they can be successfully drilled out with the throttle (or choke) shaft clamped in a machine vise fastened to the table of a milling machine, use a 3/16" center drill bit (and possibly a large magnifying glass for precision to guarantee dead center-drilling of the screw), then use a drill press with a 5/64" drill bit to finish drilling out the broken off screw. And then use a 3-48 UNC taper hand tap to clean and straighten the threads in the shaft. To install the bushing in the carburetor, clean out the counterbore, and to align the bushing perpendicular with the counterbore, slide the bushing on a 1/4" or 6mm screw or bolt, and insert the screw or bolt in the throttle shaft hole, and use small hammer or bench vise to tap- or press-in the bushing, and then reinstall the shaft. If the bushing fits somewhat loose in the counterbore, lightly tap the sides of the counterbore with a hammer to make the counterbore slightly oblong/egg-shape. And do not reuse the OEM soft brass throttle or choke plate retaining screws! Because being the threads are already "stretched" from being previously installed, they could break off while being tightened or possibly loosen and dislodge later, which can damage the valves or piston. If the screws loosen or become dislodged, the engine will not idle down.

NOTE: Usually the short, flat bronze bushing will snug up a worn throttle shaft. With oil for lubrication, the bushing and shaft should last a long time. However, the newer Walbro and the aftermarket carburetors have no counterbore for the bushing, and sometimes in these carburetors, especially the Walbro, the [upper] throttle shaft hole will wear oblong. Sometimes the throttle shaft will wear, too. When the hole wears oblong, just installing a new shaft will not fix the problem. To repair a worn, oblong hole, it must be precision align-bored precisely aligned with the [unworn] lower hole, and a bronze sleeve bushing would need to be installed along with a new throttle shaft. On other makes of carburetors, if the original shaft is worn and a new throttle shaft isn't available, then a new throttle shaft would need to be machined/fabricated. The throttle lever can be reused and welded to the new machined/fabricated shaft. And if necessary, a slightly oversized throttle shaft can be installed instead of the original diameter shaft. I can do all of these things for $50.00± each for parts and labor each, plus return shipping & handling.


Throttle Shaft Sleeve Bushings. Use each bushing listed below to repair a worn throttle shaft through-hole in carburetor body for various makes and models of small engines to prevent a vacuum leak, which can cause poor idling and engine damage at higher RPMs. Bushing and throttle shaft will last longer with the foam seal listed above. INSTALLATION: The throttle shaft through-hole in carburetor body must be precision align-bored in a vise fastened to a milling machine table according to the O.D. of bushing to be installed in exact alignment with the lower or side [blind] hole so the throttle shaft will operate freely without binding. Apply clean motor oil on throttle shaft before installing for smoother throttle operation and less wear to shaft and/or bushing.

Throttle and Choke Plate Replacement Retaining Screws Listed Below | To avoid breaking off the OEM soft brass throttle or choke plate retaining screws, use a Dremel or equivalent small rotary grinder chucked with either a chainsaw sharpening stone or an 1/8" high speed steel or carbide end mill to grind away the flared end of the screw threads until flush with the shaft, then the screws can be easily removed without breaking off. But if the screw(s) do break off, they can be successfully drilled out and the shaft can be rethreaded with the appropriate size tap for installation of new screws. And definitely do not reuse the OEM soft brass throttle or choke plate retaining screws! They can break off while being tightened, or possibly loosen and dislodge later, which can bend a valve or damage the piston and cylinder head. TIP: When installing a small phillips- or slotted-head screw to keep it from falling out of the screwdriver tip in a hard to reach place, for ordinary steel screws, temporarily magnetize the screwdriver by rubbing a magnet several times along the length of the shank, or for stainless steel screws, apply a dab of automotive grease in the head of the screw.

NOTE: The choke shaft detent ball and spring are required only for hand-operation of the choke plate to keep it in the open position on stand-alone engines without a remote cable control, such as competition garden pulling tractor, garden tiller, generator/welder, air compressor, water pump, etc. Replace if lost so the choke will stay open while the engine is running. But if the choke is operated by a cable, such as on a lawn & garden tractor for general yard and garden use, then these parts aren't needed and will serve no purpose whatsoever.

Small Engine Remote Fuel Primer Bulb System Kits. Safe to use and works flawlessly! Can be used on most general lawn and garden tractors, competition garden pulling tractors, go-karts, small motorized vehicles, or virtually any small engine equipment or snow removal equipment with a choke plate in the carburetor. Primer bulb can be installed on pedestal, dashboard, instrument panel, engine control panel, flywheel shroud, etc. Requires 1/4" mounting hole for primer bulb assembly. Works with Carter or Kohler (OEM and aftermarket), Briggs & Stratton, Tecumseh, Mikuni, Zenith, or virtually any carburetor with a float. Works with pump gas, race gas, E-85 or methanol fuels. The choice of professional garden tractor pullers everywhere! With the fuel bowl atmospheric vent opening plugged (air passageway from inside the float bowl to outside of carburetor), then with one or two pushes of the primer bulb with your finger, air pressure created within the float bowl forces fuel up through the main jet and out the nozzle, creating a slight flooding condition inside the carburetor throttle bore, allowing a cold engine to start quick. With this setup installed, the choke plate and shaft is not needed and can be removed. No more binding of a cable-operated choke and/or bent choke plate, or messy and unsafe "hand choking" of the carburetor. Being the atmospheric vent opening will be plugged, the fuel baffle splash shield in the Carter or Kohler carburetor is not needed with this setup and will serve no purpose whatsoever. Kit includes: New primer bulb assembly with integrated 1/8" barbed hose fitting and serrated mounting nut, 1/8" I.D. x 3/16" O.D. x 2' length clear vinyl hose, loop-type clamp and 1/8" diameter x 1" length brass tube. Click or tap here for installation instructions. A proven, ingenious and innovative concept by Brian Miller, because nobody else advertise the universal kit for use on various small engine equipment, lawn and garden tractors or competition pulling tractors. NOTE: If an engine is hard to start, even with the choke plate fully closed and tuned correctly, then it may need the valve clearances reset and/or professional valve job performed. The reason some older engines is hard to start is because the valve faces, especially the intake valve, wears slightly away against the valve seat, and this causes the clearance between the valve stem and lifter to be lessened, which will prevent the valve(s) from fully closing to trap adequate compression in the combustion chamber [so the engine can start easier]. This remote fuel primer system will not help an engine start easier if it needs a valve job. [Return To Previous Paragraph or Section]

    • OEM Briggs & Stratton part #'s 69221, 297866, 297866S, 392305, 393156, 395005. $9.00 each, plus shipping & handling.
  • Alcohol-resistant neoprene rubber O-ring for inside of 1-3/4" fuel/gas caps. Provides a better seal against the rim of a slightly bent or damaged filler neck on fuel tank to lessen loss of fuel when tank is full. For a better seal, pry out and install under paper-like gasket material in gas cap. Fits snug in gas cap. $1.00 each, plus shipping & handling.

FYI - If a gas cap is missing the sealing gasket, this part can be made from durable paper-like gasket material by cutting out a piece so the outside diameter fits snug inside the cap. Be sure to make a small hole (1/32") off-center in the gasket for the atmospheric vent to draw air in the tank as fuel is depleted. And if fuel spews out of the vent hole in the cap (with the gasket) with a full tank of gas due to normal engine vibration, to prevent a possible fire, place a small piece of porous foam rubber (reticulated polyurethane foam) between the gasket and vent hole in the cap. The foam will absorb the fuel and block it from being forced out the vent hole, and it'll allow incoming outside air to pass through as fuel is depleted in the tank. (A proven, ingenious and innovative concept by Brian Miller, because nobody else online mentions doing this.)

Professional Carburetor Rebuilding -

Rebuild and/or Repair YOUR Carter, Kohler or Walbro Carburetor. Nothing performs better than the OEM carburetor that originally came on the engine. This is a basic rebuild service with no "high performance" modifications performed whatsoever. Work includes: Complete disassembly of carburetor, thoroughly clean carburetor body and all associated parts in an ultrasonic cleaning machine, inspect all parts for wear, resurface both ends of carburetor body on a wide, flat belt- or disc-sander/grinder to remove warpage and restore flatness (to prevent a vacuum leak), install new overhaul/rebuild kit, and if needed, install new bronze throttle shaft bushing and/or new throttle shaft. $65.00-$135.00± for parts and labor each, plus return shipping & handling.

  • For certain types of Carter, Kohler, Walbro or various other make of carburetor not used on Kohler K-series or Magnum engines: Replace severely worn OEM throttle shaft with a new fabricated/machined steel throttle shaft and reuse OEM throttle plate and lever. $75.00 for parts and labor. An innovative concept by Brian Miller, because nobody else advertise this distinctive service.
  • Idle speed and air/fuel mixture bore will be preset on the carburetor just to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the carburetor/engine will be used, final idle and high speed air/fuel mixture will need to be made by the customer so the engine will run smooth.
  • FYI: A-1 Miller's also offer professional rebuilds of older vintage and antique/vintage carburetors virtually of any kind as long as replacement parts are available. New throttle and choke shafts can be fabricated in our shop.
  • All carburetors that A-1 Miller's repair, rebuild, modify or sell are guaranteed to be free of defects and come with a limited lifetime workmanship warranty from date of purchase. Warranty includes FREE professional and honest technical support.

IMPORTANT: When sending your carburetor to A-1 Miller's, use the USPS, FedEx or UPS with a tracking number. Package it securely so it won't get damaged and address it correctly so it won't get lost in shipping and place it in a sealed zip-lock sandwich bag to prevent the odor of gas from escaping the package and prevent the loss of any loose parts in shipping. To prevent the odor of gas from outside the package, apply air freshener on the carburetor to disguise the smell of gas. Because the USPS, FedEx or UPS will not deliver any packages that smell like gas. Also, include a note in the package with your name, complete and correct postal address, phone number (in case I have any questions), a description of what you want done, how the engine will be used and any other parts you may need. I will contact you when the carburetor (and list of parts) are ready to be sent back to you. I also do business with customers in Canada and worldwide. - Brian Miller

FYI - Many of our customers send me their carburetor for rebuilding, but sometimes I can't find anything wrong it. So I'd call our customer and ask how their engine acted or ran. After hearing their story, I tell them it sounds like their engine either needs a professional valve job performed or it needs a professional tune-up. And lo and behold! Many of them either adjusted the valve clearances or had a professional valve job performed, or performed a professional tune-up, and said that their engine ran like new again. So remember, sometimes a carburetor problem may be the valves or the ignition system instead. Please contact A-1 Miller's for FREE professional and honest technical support if you have any concerns with how poorly your engine runs.

High Quality Aftermarket Walbro-Replicated LME Carburetor. Brand new. Fits Tecumseh engine models HH100 and HH120. The OEM Walbro LME carburetor is no longer available from Tecumseh. Replaces discontinued Tecumseh part #'s 631304A, 631304B and 632424.
  • $40.00 each, plus shipping & handling.

If you're not sure what model Tecumseh engine you have, go here: Craftsman to Tecumseh Model Cross Reference.

NOTE: Before considering replacing the carburetor, the engine may have insufficient valve-to-lifter clearances or it may need a professional valve job performed instead. So check and (re)set the valve clearances to factory specifications. If there's black sooty (carbon) residue inside the carburetor throttle bore, this means the intake valve definitely has insufficient clearance. Because sometimes misdiagnosed carburetor problems can be faulty valves.

Professionally Rebuilt Genuine OEM Carter Model N #13 or #16 Carburetor. Very rare nowadays. This particular carburetor is designed specifically for Kohler engine model K90 and K91 (which are the same engine), and certain low RPM K141 engines. It has a tapered/inverted cone-shape float bowl and float, and the throttle bore measures .810" diameter and the venturi is .542" diameter. When used on a Kohler engine model K141, K160/K161, L160/L161, L181, K181 or M8, due to the smaller throttle bore and restrictive venturi, and velocity of air that's required, the bigger engine may not produce full power at 3,600 RPM. (It'll be the same as using a small 2-barrel carburetor versus a big 4-barrel carburetor on an automotive engine.) This is a plain, stock carburetor that's been completely disassembled, thoroughly cleaned and professionally rebuilt with a new overhaul kit, new throttle shaft (if needed) and other new parts if required. No performance modifications are made to this carburetor whatsoever. The idle speed and air/fuel mixture adjustments will be initially set on the carburetor just to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer so the engine will run smooth.

But due to the bigger venturi, when used on a K90/K91, K141 or K160/K161, the smaller engine may hesitate to rev up because it may not create the velocity of air or air charge required to sufficiently draw/suction fuel through the main nozzle at 3,600 RPM.

Because the USPS, FedEx or UPS will not deliver any packages that smell like gas. Also, include a note in the package with your name, complete and correct postal address, phone number (in case I have any questions), a description of what you want done, how the engine will be used and any other parts you may need. I will contact you when the carburetor (and list of parts) are ready to be sent back to you. I also do business with customers in Canada and worldwide. - Brian Miller

High Quality Aftermarket Carter Model N-Replicated Fully Adjustable Carburetor. The throttle bore in this particular carburetor measures .811" diameter and the venturi is .588" diameter. The choke lever is positioned the same as the OEM Carter Model N carburetors. This is an alternative universal low cost carburetor that is designed to be used on Kohler engine models L160/L161, L181, K181 or M8. Due to the larger venturi size, this carburetor may not work correctly on the Kohler engine models K90/K91, K141 or K160/K161. Direct replacement; no modifications to linkages required. When installing the carburetor, reuse the same linkage and everything else. Transfer the 1/8" NPT fuel hose fitting (use plumber's thread sealing tape on threads of fitting to guarantee a leak-proof seal), install carburetor on engine, adjust the idle speed and air/fuel mixtures until the engine runs smooth. Irrelevant Carter or Kohler part number(s). Comes with a limited lifetime warranty from date of purchase. Warranty includes FREE professional and honest technical support. $30.00 each, plus shipping & handling.

NOTE: Before considering replacing the carburetor, the engine may have insufficient valve-to-lifter clearances or it may need a professional valve job performed instead. So check and (re)set the valve clearances to factory specifications. If there's black sooty (carbon) residue inside the carburetor throttle bore, this means the intake valve definitely has insufficient clearance. Because sometimes misdiagnosed carburetor problems can be faulty valves.

Professionally Rebuilt Genuine OEM Carter or Kohler #26 Carburetors. The throttle bore measures 26mm/1.07" diameter and the venturi is .812" diameter. This particular carburetor is designed specifically for Kohler engine models K241, K301, K330/K331, M10 and M12. When used on a Kohler engine model K321, M14, K341, M16 or K361, due to the smaller throttle bore and restrictive venturi, and velocity of air that's required, the bigger engine may not produce full power at 3,600 RPM. (It'll be the same as using a restrictor plate, or a small 2-barrel carburetor versus a big 4-barrel carburetor on an automotive engine.) These are plain, stock carburetors that's been completely disassembled, thoroughly cleaned and rebuilt with a new overhaul kit, new throttle shaft bushing and/or new throttle shaft (if needed) and other new parts installed if required. No performance modifications made to these carburetors whatsoever. Includes choke plate installed. The idle speed and air/fuel mixture adjustments will be initially set on the carburetor to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final idle and high speed air/fuel mixture adjustments will need to be made by the customer so the engine will run smooth.

Professionally Rebuilt Genuine OEM Carter #28 Carburetor. Very rare carburetor. The throttle bore measures 28mm/1.17" diameter and the venturi is .937" diameter. This particular carburetor was designed specifically for the early Kohler engine model K321 with specification suffix "A", "B" or "C" (with the smaller 1-1/8" exhaust valve) and for certain early low RPM K341 engines. When used on a Kohler engine model K241, M10, K301 or M12, due to the larger throttle bore and bigger venturi, the smaller engine may hesitate to rev up because it may not create the velocity of air or air charge required to sufficiently draw/suction fuel through the main nozzle at 3,600 RPM. These are plain, stock carburetors that's been completely disassembled, thoroughly cleaned and rebuilt with a new overhaul kit, new throttle shaft bushing and/or new throttle shaft (if needed) and other new parts installed if required. No performance modifications made to these carburetors whatsoever. Includes choke plate installed.

It may have the part number 236636 stamped on the flange. It has been discontinued by Carter many years ago. NOTE: Not all numbers stamped on Carter carburetors are listed with Kohler.

10-18hp Kohler (or Carter [model N]) CarburetorNEW high quality Aftermarket Kohler-replicated fully adjustable carburetors. Each is a direct replacement with the same function and appearance as OEM Carter and Kohler carburetors. The choke lever is positioned the same as the OEM Carter and Kohler carburetors. No modifications required. Before installing carburetor, transfer the 1/8" NPT fuel hose fitting (use plumber's thread sealing tape on threads of fitting to guarantee a leak-proof seal), reuse same linkage and everything else, and after carburetor is installed on engine, with engine running, adjust idle speed and low and high speed air/fuel mixture screws until engine runs smooth.

If there's black sooty (carbon) residue inside the carburetor throttle bore, this means the intake valve definitely has insufficient clearance. Because sometimes misdiagnosed carburetor problems can be faulty valves. FYI: Some people advertise online that the aftermarket 1.07"/#26 carburetor, that's suited for Kohler engine models K241, M10, K301 or M12, can also be used on the K321, M14, K341, M16 and K361 engines. But I know for a fact and dyno tests shown that if the 1.07"/#26 carburetor is used on a K321, M14, K341, M16 or K361, which with the correct size carburetor (1.2"/#30 and 1.25"), produces 14hp, 16hp and 18hp, respectively. Only the K321 and M14 engines require the 1.17"/#28 carburetor for it to produce 14hp at 3,600 RPM. But with the 1.17"/#28 aftermarket carburetor installed on the K341, M16 and K361 engines, they will produce about 14hp and 15hp at 3,600 RPM, and make less torque, because the engine would be drawing less air through the smaller throttle bore and not build up as much compression. Aftermarket carburetors are not available with the 1.2"/#30 or 1.25" throttle bore, that's suited for the K341, M16 or K361 engines. Other sellers apparently don't know the difference between the OEM and aftermarket carburetors because these look virtually identical on the outside. Or maybe the seller figures what most people don't know, makes them more money. So buyer beware!

A-1 Miller's Professional Repair Service - Professional Stock-Appearing, "Old School" Technology, High Performance Carburetor Modifications - Modify YOUR OEM Carter or Kohler #26 or #30 carburetor for enhanced performance on a competition garden tractor pulling engine. [Top of Page]

The carburetor is modified for maximum performance to increase airflow into the combustion chamber. Stock-appearing means Carter or Kohler #26, #28 or #30 carburetor (except Walbro) is modified internally to improve engine performance. The venturi is bored-out to .995", 1" or straight-through design (to match the diameter of throttle bore) or whatever your club's sanctioning rules allow for use with pump gas, E85 or methanol fuel. Please specify if your engine has stock size valves or an oversize intake valve. And A-1 Miller's may need a copy of your association's/club's sanctioning rules regarding the legality of the carburetor so when we rework/modify it, it'll be legal for the class you plan to pull in. The idle speed, idle air/fuel mixture and high speed air/fuel adjusters will be initially set on the carburetor just to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final adjustments will need to be made by the customer so the engine will run smooth. All carburetors that A-1 Miller's repair, rebuild, modify or sell are guaranteed to be free of defects and come with a limited lifetime workmanship warranty from date of purchase. Warranty includes FREE professional and honest technical support. FYI - After I modify/rework a Carter or Kohler carburetor for high performance use, as long as everything else are all in good condition with the engine, including the ignition timing, valve train, etc., the carburetor will, without a doubt, perform flawlessly. - Brian Miller

  • Bore-out and rework carburetor for improved performance. $85.00 labor each, plus return shipping & handling. Extra charge if any missing, worn beyond reuse or broken parts are required.
  • Before the venturi can be bored-out, the main jet/nozzle must be removed. If it is stuck and must be drilled out, there is an extra $50.00 charge. This includes the price of a new main jet/nozzle.
  • If the carburetor needs a bushing for the throttle shaft installed, there is an extra $10.00 charge. Or if it needs a new throttle shaft and bushing, there is an extra $40.00 charge.
  • Convert carburetor to bottom main fuel adjuster. (Only for open RPM/wide open throttle operation competition pulling engines). $17.00 extra.
  • No extra charge to convert your carburetor for use with E85 or methanol fuels with the high performance modifications.
  • NOTE: All high performance carburetors that A-1 Miller's modify (bore-out and rework) are guaranteed to allow the engine to rev up at its full potential. If the engine will not rev up fully, and a high-output/performance ignition coil and a medium capacity (OEM/ordinary) condenser are being used, which can result in a weak spark, then the coil needs two medium capacity condensers or one high-capacity/performance condenser to produce a stronger spark.


Fully Adjustable Competition Pulling #26 and #30 Carburetors Bored-Out and Reworked for High Performance Use. The carburetors listed below will help your tractor pull strong on the track! A bored-out venturi and reworked carburetor is when the carburetor is modified for maximum performance for general yard and garden use, and/or for competition pulling. These carburetors have been modified by Brian Miller to outperform an OEM stock Carter or Kohler carburetor under heavy competition pulling load, and when adjusted correctly, may not run lean at high RPM while going down the track. Stock externally appearing will pass tech with virtually any pulling association or club. The venturi in these carburetors are bored to either .995", 1" or 1.2" straight-through throttle bore for open RPM, setup for gas, E85 or methanol fuels, whatever your club's sanctioning rules allow or whatever you desire for all-out engine performance. Please specify if engine has stock size valves or an oversize intake valve. The idle speed, idle air/fuel mixture and high speed air/fuel adjusters will be initially set on the carburetor just to get the engine running, but due to the altitude level, atmospheric/barometric pressure and air temperature where the engine will be used, final adjustments will need to be made by the customer so the engine will run smooth. All carburetors that A-1 Miller's repair, rebuild, modify or sell are guaranteed to be free of defects and come with a limited lifetime workmanship warranty from date of purchase. Warranty includes FREE professional and honest technical support.

NOTE: All carburetors are "built to order." So when placing an order, please specify if your engine has a factory stock size or oversize intake valve, if you want it with a .995" or 1" venturi, or a straight-thru throttle bore (no venturi), if the engine is going to turn 4,000± RPM or open RPM/wide open throttle operation, and if you want the choke plate/shaft installed.

  • OEM Kohler #26 carburetor or high quality aftermarket Kohler-replicated #26 reworked carburetor with venturi bored to .995" (NQS legal), 1" or 1.07" with top main fuel adjuster when sanctioning pulling rules require this size venturi. Recommended for up to 4,000 RPM and/or with stock size valves. $100.00 each outright, plus shipping & handling.
  • OEM Kohler #30 reworked carburetor with venturi bored to 1.2" with top main fuel adjuster. Recommended for up to 4,000 RPM and/or with stock size valves. This size carburetor not available in aftermarket.

NOTE: All high performance carburetors that A-1 Miller's modify (bore-out and rework) are guaranteed to allow the engine to rev up at its full potential. If the engine will not rev up fully, and if a high-output/performance ignition coil and a medium capacity (OEM/ordinary) condenser are being used, which can result in a weak spark, then the coil needs two medium capacity/OEM condensers or one high-capacity/performance condenser to produce a stronger spark.

12 Volt Electric Fuel Pump Installation Kits. Compact and small. Use an electric fuel pump when the gas tank is lower than the carburetor or when a mechanical fuel is insufficient. Alcohol-resistant and very durable. Upgrade to one of these electric pumps for more reliable fuel delivery. Instantly fills the carburetor with fuel as soon as pump is powered up. Ideal when equipment runs out of gas and no need to crank the engine for a long time with a pulse-type/vacuum-operated or a mechanical fuel pump to refill the carburetor to restart the engine. Saves wear and tear of the starter motor and reserves battery power. Convert from gravity feed, or replace a faulty or inefficient pulse-type/vacuum-operated fuel pump or malfunctioning or inefficient mechanical fuel pump. For most small engines, a fuel regulator is not required with the low pressure pumps. Each is suitable for small gas engines up to 4 cylinder carbureted engines. Use on general lawn and garden equipment, go-karts, ATV's, UTV's, small motorized vehicles or competition garden pulling tractors with a stock engine or open RPM competition pulling engine. Will work with most small gas engines such as Kohler, Briggs & Stratton, Tecumseh, Wisconsin, etc., and on virtually all models of Cub Cadet, John Deere, Wheel Horse, Sears Suburban, Massey Ferguson, and just about any lawn & garden equipment with a 12 volt electrical system. If it's a Kohler AQS "Quiet Line" engine, the [larger] fuel hose fitting in the carburetor will need to be changed to a 1/4" fitting. IMPORTANT: Use plumber's thread sealing tape to guarantee a leak-proof seal. If the engine has magneto or solid state electronic ignition, and no charging system, a small 12 volt battery will need to be used to power the fuel pump. The battery would need to be recharged with a 120 volt portable battery charger from time to time so the fuel pump will work at peak efficiency. Each fuel pump draws less than 2 amps. Wire Connections: The RED wire connects to the IGNITION terminal on the ignition/starter key switch or to an OFF-ON toggle switch, and the BLACK wire connects to negative (–) ground (chassis or frame). NOTE: Electric fuel pumps listed here come with a lifetime warranty from date of purchase. IMPORTANT: Install the inline fuel filter between fuel tank and pump inlet port to prevent any dirt/debris from wearing the pumping mechanism. If dirt/debris become lodged in pump, it can be cleared-out with 150± P.S.I. compressed air and an air blow gun nozzle when applied in the reverse direction of fuel flow. And for long term storage of equipment, drain and flush out all fuel, leave fuel hoses disconnected and apply light oil in the pump to prevent oxidation or "sticking" of the pumping mechanism.

FYI - About the air cleaner assembly on the Kohler K90/K91 engine with the Carter Model N #13 or #16 carburetor shown above, being the OEM Kohler air cleaner assembly and individual components are no longer available, and used OEM Kohler air cleaner assemblies or components in good condition are extremely hard to find nowadays and/or is cost prohibitive, the lower priced and readily available OEM Tecumseh air cleaner assembly shown on the Kohler K91 engine above will fit this engine with one modification that needs to be made. The center of the [plastic] mounting adapter will need to be bored-out/enlarged to match the diameter of the inlet opening of the carburetor to allow the engine to draw plenty of air. This air cleaner assembly includes a pleated paper air filter element (part # 35066), plastic twist-on cover (part # 35065), plastic mounting adapter (part # 35797), and mounting gasket (part # 27272A). Two 8-32 UNC screws with two small spacers and two flat washers w/lock washers and gasket are also needed to securely fasten the adapter to the carburetor. And the OEM Tecumseh air cleaner assembly shown to the right (part # 730164), which includes a pleated paper air filter element, metal cover, and metal mounting plate, will also fit this engine with no modifications whatsoever. A proven, ingenious and innovative concept by Brian Miller, because nobody else online mentions doing this. The OEM Kohler air cleaner assemblies for Kohler engine models K141, K160/K161, KV161, L160/L161, L181 and K181 will also fit the K90/K91 engine carburetor.

Packaged item(s) weighing over 1 lb. and up to 66 lb. is sent by US Postal Service Airmail Parcel Post for a 4-10 days delivery. I cannot use the US Postal Services' Flat Rate Priority Mail envelopes and boxes to ship outside U.S. territories. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground or equivalent services. We try to keep our shipping cost to customers within reason. Therefore, we don't ship our products in a fancy-looking package with our company name and/or logo on it because most customers will just toss it in the trash after they remove the contents. And being there is no USPS tracking number outside the US, all I can do is make sure I write your address correctly on the customs form and on your package.
