NOTE: When installing, ALL brass floats need to be adjusted. They don't come preset. To adjust the float, remove the carburetor and float bowl, turn the carburetor upside-down, and set the float level with the carburetor body. To set the float level, use a small flat screwdriver to bend the tang that rest against the float valve. Then make sure it moves up and down without binding.
New plastic float for Walbro WHG and WHL carburetors that's used on all late Kohler Magnum single- and twin-cylinder cast iron flathead engines.

New brass main nozzle. Fits all Carter and Kohler #26, #28 and #30 carburetors used on the Kohler K-series and early Magnum single cylinder 10hp-16hp flathead engines, 18hp OHV and twin cylinder cast iron flathead engines. This particular part is not available from Kohler. Professionally CNC machined in the USA . Drilled for gas. $15.00 each, plus shipping. NOTE: When rebuilding a plain, stock Carter or Kohler carburetor, there is no need to remove the main nozzle! If the main nozzle won't come out, then don't worry about it. All you have to do is make sure the bottom hole is open. But if you're modifying a carburetor to bore the venturi, then the main nozzle will need to be removed. And unfortunately, sometimes they get stuck in place and the screwdriver slot strips out. (I hate when this happens.) I found the only way to remove them is by drilling them out. Because soaking it with penetrating oil or using a small blunt punch to rotate it counterclockwise does not help at all.
New brass high speed main fuel adjuster needle valve. Fits Carter model N carburetor used on 4, 7 and 8hp Kohler single cylinder cast iron block flathead engines. Replaces Kohler part # 200410, 200410-S. Professionally CNC machined in the USA . Has lower hole enlarged and holes midway blocked. $13.00 each, plus shipping.

Throttle Shaft Bushings -
IMPORTANT!! 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. More than .010" of play is considered too much for throttle shaft wear. Plus, at operating running speeds (3,600 rpms), 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 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 loose 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 bushingBRONZE throttle shaft bushing for the Carter model N carburetor used on the Kohler 4hp, 7hp and 8hp (models K90/91, K141/K161 and K181) flathead cast iron block engines. These bushings are CNC machined in the USA and fit perfectly! Dimensions are either: .213" or 7/32" (.219") i.d. x .407" o.d. x 1/8" width. $5.00 each, plus shipping. NOTE: Some of these carburetors have a different diameter throttle shaft. It's either .213" (#3 number size [drill bit]) or 7/32"(.219"). Please measure shaft accurately before ordering. Also, not all Carter model N carburetors will accept a bushing. (No counterbore.) So please check your carburetor before ordering.
  • BRONZE throttle shaft bushing for the #26, #28 and #30 Carter, Kohler and early Walbro carburetors used on the Kohler 10hp through 16hp flathead and 18hp OHV cast iron block engines. These bushings are CNC machined in the USA and fit perfectly! Dimensions: 7/16" o.d. x 1/4" i.d. x 1/8" width. $4.00 each, plus shipping.
    • Installation instructions: The old throttle shaft must be reused with the above bushings. The bushing makes contact with the upper unworn part of the shaft. To install the throttle shaft bushing, remove the two tiny screws that secures the throttle plate to the shaft, then lift the shaft out of the carburetor body. Clean out the counterbore and use a 3/16" or 1/4" bolt and small hammer to squarely drive the bushing into the counterbore of the carburetor body and reinstall the shaft. Should one or both of the tiny brass screws break off while being removed, sometimes the shaft can be difficult to remove. To remove the shaft, grind the flared end of the [broken] stud enough where they are flush with the throttle shaft. A Dremel or equivalent grinder with a small chainsaw sharpening stone works best. Then the broken stud must be drilled out of the throttle shaft with either a 5/64", #46 or 2mm drill bit and retap the threads. The stock 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) must be installed. In this event contact me and I will send you the larger screws with split lockwashers.
    • Additional note: Usually, the throttle shaft bushing will snug up a worn throttle shaft. The bushing will last a long time, too. But sometimes the hole in the carburetor body where the throttle shaft fits into will wear also. When this happens, a new shaft won't fix the problem. The hole must be accurately bored and a longer bushing must be installed with the new shaft. But if a new throttle shaft isn't available for your particular carburetor, then one must be machined from scratch. And if necessary, if the carburetor body is worn, it can bored for installation of a longer bushing to snug the new shaft, or a slightly oversized shaft can be installed instead. I can do this for $35.00-$45.00 (depending on type of carburetor), plus return shipping, if interested.
  • And as for the newer style Walbro carburetor without the counterbore for installation of an 1/8" tall bronze bushing, I can accurately bore the carburetor body for installation of a long upper bronze bushing and then if it needs it, I'll install a new throttle shaft. (I've done this before many times with great results.)
    • $50.00 installation of bushing and labor only (without new throttle shaft), plus return shipping.
    • $75.00 with new throttle shaft, installation of bushing and labor, plus return shipping.
Stainless steel throttle and choke plate retaining screws with split lock washers for all Carter, Kohler and Walbro carburetors that's used on the Kohler K-series and early Magnum cast iron flathead engines. Tensile strength: 60,000 psi. Sizes available: 3-48 NC (most common; .096" diameter) and 4-40 NC (.109" diameter) x 1/4" length. Please specify which size you need. .50¢ per pair, plus shipping. Other small screw sizes are also available. Please contact me and I'll see if I can get what you need at a reasonable price. NOTE: When the two tiny brass screws are removed from the throttle shaft for installation of the throttle shaft bushing, one or both of them may break off. If this happens, the remaining protruding threads in the shaft will need to be ground down so the shaft can be removed from the carburetor body. Then the broken screw(s) in the shaft will need to be drilled out (preferably in a drill press) with a 5/64" drill bit and the threads recut so the new screw(s) will thread in with no problems. I know about all of this from years of experience. Or, if you want, I can completely rebuild your carburetor for $60.00 parts & labor plus return shipping.
New throttle shaft repair kit for Kohler carburetors used on the Kohler K-series and early Magnum cast iron block single cylinder 10hp-16hp flathead and 18hp OHV single cylinder engines. Replaces Kohler part # 25-757-16, 25-757-16-S and Gravely 214997. Made in USA . Kit includes steel throttle shaft, bronze throttle shaft bushing, throttle shaft bushing installation tool, one #2-56 NC screw, three 3-48 NC screws and Loctite. $35.00 each, plus shipping. Part # 055-329
NOTE: New shaft has no lever - you must reuse the old one. This kit is designed for the Kohler carburetor, like the one on the right, and not the older Carter carburetor having the short throttle shaft with the aluminum clamp-on lever and a flat on one side of the shaft. For the Carter carburetor, use the bronze bushing above.

Note: I set all of the carburetors that I rebuild somewhat close just so the engine will start and run, but because of the attitude and engine design, you'll have to make the final adjustment. And the carburetors that I sell come with a 30 day workmanship warranty and are guaranteed to be free of defects. Other carburetor services listed further down in the web site.


New and Reconditioned Fuel Pumps - NOTE: Repair kits for Kohler mechanical fuel pumps are no longer available. Your only options are to find a good used fuel pump or purchase a new one.
New mechanical plastic body "new style" fuel pump for Kohler K-series, Magnum 10hp-16hp (flathead) and 18hp OHV single cylinder cast iron block engines (replaces Kohler part # A235845, 47-559-04S) $45.00 each, plus shipping. Part # 22-10211


New mechanical plastic body "new style" fuel pump for Kohler flathead twin cylinder KT17, KT19, and M18, M20 Magnum series engines (replaces Kohler part # 52-559-01S, 52-559-02 & 52-559-03.) $45.00 each, plus shipping.


Many more mechanical and vacuum-operated fuel pumps for other makes and models of engines are also available. Please call or email me for your needs. More parts may be added later. Please contact me if you're interested in any of the above parts. And the mechanical Kohler fuel pump with the primer lever is no longer available from any of my suppliers. The only pumps I can get are the ones without the lever. This is disappointing because sometimes the lever is needed when the engine runs out of gas and the primer lever can be used to manually pump the fuel to the carburetor. This comes in handy because without the lever, the engine would need to be cranked a lot (this is not good for an electric starter) just to pump the fuel the carburetor.
