What It Is

This is an aftermarket carburetor designed for Kohler Courage single-cylinder engines in the 22–27 HP range, commonly found on zero-turn mowers, lawn tractors, and commercial walk-behinds. It replaces worn fuel mixing and delivery components to restore engine performance.

Fitment & Compatibility

Before buying, confirm your engine model is one of these: SV720, SV725, SV710, SV715, SV730, SV735, SV740, SV810, SV820, SV830, or SV840 (Courage Series). Check the engine number plate (usually stamped on the blower housing or valve cover). This carb replaces OEM part numbers 32-853-12-S, 32-853-08, 32-853-06, 32-853-04, and 32-853-08-S. It does not fit Kohler Command or other series. Verify the mounting bolt spacing (typically 2.5 inches center-to-center) and the bowl drain orientation—some models have a slightly angled fuel inlet. If your mower uses a pulse-style fuel pump, ensure the carb’s fuel inlet matches your pump outlet size (usually 1/4 inch barb).

Key Things to Know

• Quality variance: This is a budget aftermarket part. Expect thinner gaskets and less precise casting than OEM. Some units may need light deburring of the throttle shaft or float adjustment.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel line, and throttle/governor linkage. Keep track of spring positions—take a photo before disassembly.
• Common gotcha: The supplied gaskets may not seal perfectly. Use a thin layer of gas-resistant sealer on the base gasket. Also, the main jet is often fixed; if your engine runs lean or rich, you may need to rejet (not user-adjustable on this model).
• Tuning tip: After install, set the idle mixture screw (if adjustable) to 1.5 turns out from lightly seated, then fine-tune for best idle.

Should You Buy It

Buy this if you need a quick, low-cost fix for a non-running Kohler Courage engine and you’re comfortable with basic carburetor tuning and potential minor fit adjustments. It’s not for you if you want OEM reliability, need exact emissions compliance, or have a high-hour commercial mower that demands a better-built replacement.
