price! $4.00 each, plus shipping.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. Replaces (OEM): Kohler #25 757

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

carburetors. Made of steel. .25¢ each, plus shipping. Requires
1/8" NPT taper pipe tap to create threads.

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. 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. |

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 # 055-329NOTE: 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. |

Professional Carburetor Rebuilding Service -
YOUR 10hp-18hp Carter, Kohler or Walbro carburetor professionally
reconditioned for general yard use or your Carter or Kohler reworked for
high-performance use with either gas or methanol fuel for use on a Stock,
Stock-Altered, Missouri Super-Stock or Pro-Stock pulling engines.IMPORTANT: When or if sending your carburetor to me, package it securely so it won't get damaged in shipping and please include a note in the box with your name, complete mailing address, phone number (in case I have any questions) and a description of what you want done. 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 box, 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. Carburetor Work: For a basic rebuild only with no "high performance" modifications whatsoever, the price is $40.00 labor, plus return shipping. Any additional parts or services are an extra charge. Work includes whatever parts and services it may need that's listed below. Basic Rebuild Includes:
High-Performance Upgrade for Gas, E-85 or Methanol fuels - $100.00 labor, plus return shipping. Work includes whatever parts and services it may need that's listed below. High-Performance Modifications Includes the Above Work, Plus: ü Bore the venturi to match the diameter of the throttle bore or 1" limit (.995" NQS legal size) 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're planning to pull in. |
Professionally Rebuilt Carburetors For Sale -
Rebuilt to OEM specs, Carter
model N carburetors for models K141/K161 (7hp), K181, M8 (8hp) Kohler K-series
and Magnum cast iron block, flathead engines. These are plain, stock carburetors
that's been completely disassembled, then soaked and cleaned with Chem
Dip® Carburetor and Parts Cleaner and if necessary, thoroughly
clean it afterwards with bead blaster (if the paint will come off). All fuel
passageways cleared, new parts and a new throttle shaft and/or bushing are
installed if necessary. There are no modifications made to these carburetors
whatsoever. [When available.]
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
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. |
