NOTE: All parts listed here are NEW, unless otherwise stated. The aftermarket parts are of very high quality. I do not sell cheap junk! As a matter of fact, many "OEM Kohler parts" are made in China, and Kohler owns some of the factories that make the parts in China. And I think there's no or very little difference between the aftermarket or OEM Kohler brand parts, being many of them are made in China. Kohler just charge more because they have their name on it. And as far as some parts being no longer available - either the parts didn't sell well or the EPA is trying to phase out parts for the old cast iron block flathead engines because they produce more air pollution than the newer OHV engines.

To check if the side holes are open, simply spray carburetor cleaner or WD-40 or carburetor cleaner (in an aerosol spray can) through the small hole just under the choke plate and observe if the spray exits out the main jet/nozzle inside the throttle bore and bottom of carburetor. But if modifying a carburetor to bore the venturi, then the main nozzle will need to be removed. Click here for how to remove the main jet/nozzle. $15.00 each, plus shipping & handling.

Throttle Shaft Bushings -
A worn throttle shaft is the #1 cause of most engines wearing out prematurely. If a carburetor has a worn throttle shaft, this will create a vacuum leak and the engine will idle poorly, if at all at times. Not to mention the engine will also draw in dirty air, causing wear on the valve faces/seats and piston rings, and engine will burn oil. More than .010" of play is considered too much for throttle shaft wear. Plus, at operating running speeds (3,600 rpm), the extra air will cause the engine to run lean on fuel, which will overheat the combustion chamber and cause the cylinder head to warp (blow a head gasket) and the piston and rings to wear prematurely, eventually resulting in severe engine wear and excessive oil burning. Along with regular maintenance, repair of a worn throttle shaft is required to help an engine last a long time. The most accurate way to check for amount of wear is to use a dial indicator.
  • Bronze throttle shaft bushing Bronze Throttle Shaft Bushing for the #18, #20 & #22 Carter model N carburetor used on the Kohler K90/K91 (4hp), K141 (6¼hp), K160 (6.6hp), K161 (7hp) and K181/M8 (8hp) flathead cast iron block engines. Professionally made in the USA of precision CNC machined bearing bronze. Dimensions: .407" o.d. x .213" i.d. x 1/8" height. $6.00 each, plus shipping & handling.
    • NOTE: Some Carter model N carburetors have a different diameter throttle shaft. It's either .213" (#3 [drill bit]) or .219" (7/32"). If it's the bigger size, then the bushing will need to be carefully enlarged with a 7/32" drill bit. Also, not all of these carburetors have the counterbore to accept a bushing. If there's no counterbore, then either a new throttle shaft (see belowÊ) will need to be installed, or the shaft hole will need to be enlarged to match a fabricated oversized throttle shaft. I offer this service, too.
  • Bronze throttle shaft bushing Bronze (Short) Flat Throttle Shaft Bushing for all #26, #28 & #30 Carter and Kohler carburetors used on Kohler K-series and early Magnum models K241 (10hp), K301 (12hp), K321 (14hp), K330/K331 (12½hp), K341 (16hp) flatheads, K361 (18hp OHV) and twin cylinder cast iron block engines. Professionally made in the USA of compressed bearing bronze. Dimensions: 7/16" o.d. x 1/4" i.d. x 1/8" height. $5.00 each, plus shipping & handling.
    • FYI - Bearing bronze is very hard, porous, absorbs oil and lasts a long time when lubricated regularly and used as a bushing. Brass, on the other hand, is soft, non-porous and wears quickly when used as a load-bearing bushing.
    • Installation Instructions: If it isn't severely worn, the original throttle shaft can be reused with the above bushings. The bushing makes contact with the upper unworn 1/8" area on the shaft. To install the bushing, remove the two small brass screws that secures the throttle plate to the shaft, then remove the shaft from the carburetor body. Clean out the counterbore and depending on the size of carburetor, use a 3/16" or 1/4" bolt and small hammer to squarely drive the bushing into the counterbore, and then reinstall the shaft. To prevent breaking off the throttle (or choke) plate screws, grind the flared ends with a Dremel or equivalent small grinder chucked with a chainsaw sharpening stone. Should a screw break off while attempting to remove it, sometimes the shaft can be difficult to remove. In this case, use the Dremel to grind the flared end of the [broken] screw so it is flush with the throttle shaft. Then the shaft can be removed, and the broken screw can be drilled out with either a 5/64", #46 or 2mm drill bit and retap the threads. The OEM screw size is 3-48 NC. Should the threaded hole become enlarged from drilling out the broken screw, then a larger screw (4-40 NC) will need to be installed. In this event, contact me and order the larger screws with split lock washers. Loctite is not required. The bronze bushing is easy to install. Just clean out the counterbore and slide the bushing on a short 1/4" bolt (to guide the bushing straight into the hole), place the bolt with the bushing in the hole and use a medium size hammer to drive it in until it bottoms out. Then apply motor oil on the throttle shaft before installing it and rotate it so it'll move freely in the bushing.
    • Additional Note: Usually a bronze bushing will snug up a worn throttle shaft. The bushing should last a long time, too. If the bushing fits somewhat loose in the counterbore, tap the sides of the counterbore with a hammer to close it up slightly. In other words, make the counterbore slightly egg-shaped. But don't mash the metal in too much. Just a slight tap on either side should do. But the newer Walbro carburetors have no counterbore for the bushing. Therefore, sometimes the throttle shaft hole in the carburetor body will wear, too. When this happens, installing a new shaft won't fix the problem. The hole must be accurately bored and a bronze sleeve bushing will need to be installed with a new shaft, or if the hole is not worn, sometimes the original shaft can be reused. But if the original shaft is worn and a new throttle shaft isn't available for a particular carburetor, then one must be machined from scratch. And if necessary, a slightly oversized shaft can be installed instead of the original diameter shaft. I can do this for $50.00 parts and labor, plus return shipping & handling.
  • Bronze Sleeve Bushing. This bushing is for the newer style 10hp-16hp Walbro WHG carburetors that have no 1/8" depth counterbore. NOTE: The throttle shaft hole must be precision bored larger for installation of this bushing. Dimensions: 1/4" i.d. x .313" o.d. x 3/4" long. $5.00 each, plus shipping & handling.
  • Install bronze sleeve bushing in your carburetor. $35.00 labor, plus return shipping & handling. Does not include new throttle shaft.
  • By the way - bearing bronze is porous, very hard, and lasts a long time when lubricated and used as a bushing. Brass, on the other hand, is soft, non-porous and wears quickly when used as a bushing.

Professional Carburetor Rebuilding Service -

FYI: We can professionally rebuild older vintage and antique carburetors virtually of any kind as well as newer ones, as long as replacement parts are available. We also have the capability to fabricate new throttle and choke shafts. Please contact me if you have any questions.


Carburetor Repairs - YOUR 10hp-18hp Carter, Kohler or Walbro carburetor: FYI - Many of my customers send me their carburetors for rebuilding, but lots of times I couldn't find anything wrong them. So I'd call my customers just before returning their carburetor asking how their engine acted. And after hearing their story, I told them that their engines might need a valve job performed instead. And lo and behold! Many of them either adjusted the valves or had a professional valve job performed and said that their engines ran like new. I'm not saying this happens with all engines, only the majority of them.

Modifications for the 10-18hp Kohler CarburetorBasic rebuild with no "high performance" modifications whatsoever, according to the condition of the carburetor, the repair price is minimum $55.00 for parts and labor, plus return shipping & handling. This includes cleaning carburetor and installing a new overhaul kit. Any additional parts or services are an extra charge. Work includes whatever parts and services it may need that's listed below. IMPORTANT: When sending your carburetor to me, please package it securely so it won't get damaged in shipping and include a note in the package with your name, complete mailing address, phone number (in case we have any questions), a description of what you want done and any other parts you may need. And be sure to enclose it in a sealed zip-lock sandwich bag to prevent the gas odor from escaping the package. If the odor of gas can still be smelled from outside the package, then apply perfume or cologne on the carburetor to disguise the smell of gas. Because the US Postal Service or other delivery services will not deliver any packages that smell like gas. And we'll call or email you when it's repaired.

Basic Rebuild Includes:

ü Completely disassemble and clean carburetor.
ü Resurface mounting flange and choke end.
ü Enlarge the lower hole on the high speed needle adjuster so the engine will start easier and idle better.
ü Install new overhaul kit.
ü If needed, $25.00 extra to install a new bronze throttle shaft bushing.
ü If needed, machine carburetor body and install bronze sleeve bushings for worn choke shaft holes, reuse original choke shaft. $25.00 for new bronze bushings and labor.
ü If needed, for a carburetor with the round air filter housing assembly with stripped 10-32 NF air filter housing mounting threaded hole(s), install three oversize 12-24 NC screws and lock washers. (Mounting holes in air cleaner base will need to be drilled to 7/32" for these bigger screws.) $9.00 for parts and labor.
ü Or if needed, for a carburetor with the oblong air filter housing assembly (Quietline) with stripped air cleaner mounting hole(s), drill holes deeper, cut threads deeper and install longer 10-32 NF mounting screws with lock washers. $9.00 for parts and labor.

High-Performance Modification on #26, #28 or #30 Carter and Kohler carburetors for use with Gas, E-85 or Methanol fuels - $85.00 labor, plus return shipping & handling. Work includes what's listed above plus whatever parts and services it may need that's listed below.

High-Performance Modifications Includes Everything Above, Plus...

ü Bore venturi to a 1" limit (.995" NQS legal size), straight-through design (to match the diameter of throttle bore) or whatever your club's sanctioning rules allow. Read your rules carefully to make sure! I'll need a copy of your club's sanctioning rules regarding the legality of the carburetor, so when I rework it, it'll be legal for use in the class you plan to pull in.
ü Leave choke plate/shaft intact or remove them and plug shaft holes. If your rules require a working choke or if you wish to have a working choke, please let me know and I will not remove it.
ü Add $15.00 for converting to bottom main fuel adjuster.
ü Missing, worn or broken parts are extra charge.

NOTE: If the throttle shaft and/or throttle shaft holes is/are worn in your carburetor, the carburetor body will need to machined for installation of a fabricated/oversize throttle shaft. I've performed many throttle shaft repairs on carburetors just like these in the past with success. If you're interested, I can repair yours as well. For dimension measurements, I will need the complete carburetor with the throttle shaft and throttle plate. The repair price is $65.00 for parts & labor, plus return shipping & handling. Please contact me if you're interested in this repair service.

Rebuilt, reworked and modified only for high-performance use, #26 Carter or Kohler carburetors. The venturi in these carburetors can be bored so they'll have either a 7/8", 1" (.995" NQS legal) venturi or a 1.07" straight-through throttle bore for high rpm operation, setup for gas, E-85 or methanol fuels, whatever your club's sanctioning rules allow or whatever you desire for all-out engine performance. These carburetors are completely disassembled, then thoroughly cleaned. All fuel passageways cleared, new parts and if necessary, a new throttle shaft and/or bushing are installed.

NOTE: These carburetors are designed for use on Stock and Stock-Altered pulling engines with a stock size or an oversize intake valve. Also, a high-performance carburetor is designed solely for a high-performance engine. Just bolting on a high performance carburetor is not how to gain more power and torque for a stock engine. If your engine is not a high-performance engine built to race specs, then it will not benefit from a high-performance carburetor whatsoever. These carburetors will not allow a stock "factory-built engine" to produce lots of power just by bolting it it on. Everything in the engine MUST work together to prevent air restriction or a "bottleneck" to slow down air flow. With a bigger carburetor, the engine needs to breath A LOT more air in and out of the combustion chamber. This means the intake and exhaust ports will need to be made bigger, the valves reworked for more airflow, a bigger cam will need to be installed, and the ignition system will need to be up to standards.

Also, these 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 straight-thru throttle bore (no venturi) or a 1" (.995" NQS legal) venturi, if the engine is going to turn around 4,000 rpm or at wide open throttle, and if you want the choke plate/shaft installed.

All rebuilt carburetors that we service and sell come with a 30 day workmanship warranty and are guaranteed to be free of defects.
