What It Is

This is an aftermarket carburetor replacement for Kohler V-twin engines (22–27 HP) used in Toro lawn tractors. It delivers the correct fuel-air mixture to keep the engine running smoothly when the original carb clogs, leaks, or fails.

Fitment & Compatibility

Before buying, verify three things:

• Engine model: Fits Kohler Courage, Command, and Pro models in the 22–27 HP range (e.g., CV22, CV25, CV27). Check your engine’s spec number (stamped on the blower housing or valve cover).
• OEM cross-reference: Directly replaces Toro part numbers 32-853-12-S, 32-853-08, 32-853-06, 32-853-04, and 32-853-08-S. If your original has one of these numbers, this carb fits.
• Physical check: Measure mounting bolt spacing (center-to-center) – should be 2.5 inches. Also confirm the fuel inlet and choke linkage match your setup. This is an aftermarket part, not OEM, so minor adjustments to gaskets or linkages may be needed.

Key Things to Know

• Quality varies – This is a budget carb. It often works out of the box, but some units have rough castings or sticky float needles. Inspect the bowl gasket and float movement before installing.
• Installation is straightforward – Basic hand tools, a new fuel filter, and fresh gas are all you need. Expect 30–60 minutes. You may need to swap over the original choke linkage or throttle spring.
• Common gotchas – The included gaskets may be thinner than OEM; if you get a vacuum leak, reuse the old gaskets or add a thin layer of gasket sealer. Also, the fuel inlet fitting might be slightly different – check thread size (usually 1/4″ NPT) before tightening.
• Tune-up recommended – After install, adjust the idle mixture screw (usually 1.5 turns out from lightly seated) and check for smooth idle. A carb rebuild kit (sold separately) is not needed unless you want spare gaskets.

Should You Buy It

Buy this if your Kohler-powered Toro tractor won’t start or runs poorly due to a clogged or leaking original carb, and you want a low-cost fix that usually works. Skip it if you need a guaranteed OEM match for a commercial mower or if your engine has significant internal wear – in those cases, spend more on an OEM carb or a full rebuild kit.
