What It Is

This is a complete carburetor replacement kit for Kohler Courage SV-series engines (SV710–SV830) found on Craftsman and Toro lawn tractors, mowers, and zero-turns. It replaces the original carb assembly when the engine surges, stalls, or won’t start due to clogged jets or worn gaskets.

Fitment & Compatibility

• Engine models: Kohler SV710, SV725, SV730, SV735, SV740, SV830 (23–27 HP). Check your engine’s model number tag—usually stamped near the flywheel or under the air filter.
• OEM cross: Replaces Toro 32-853-08, 32-853-06, 32-853-04, and 32 853 12-S. Aftermarket part, not genuine Kohler.
• Machine fit: Works on Craftsman LT1000/2000/3000 series, Toro TimeCutter/Z-Master, and other brands using these Kohler engines. Not for Kawasaki or Briggs engines.
• Measurements: Physical dimensions match OEM—about 4.5” x 3.5” x 3”. Ensure fuel line diameter (usually 1/4” or 5/16”) and mounting bolt spacing (2.75” center-to-center) match your old carb.
• What to verify: Engine series prefix (SV, not CH or Command). Check your old carb’s gasket shape—this kit includes a flat gasket, not a paper or O-ring style.

Key Things to Know

• Quality: Aftermarket, not OEM Kohler. Most users report it works fine, but a small percentage note slightly lean idle or misaligned float tabs—check and adjust the float height (usually 0.25–0.30”) before installing.
• Installation difficulty: Moderate (2/5). You’ll need a screwdriver, socket set, and maybe a small file to clean the mounting surface. Expect 30–45 minutes.
• Common gotchas: The included fuel line may be too short for some setups—reuse your old line if needed. Don’t overtighten the bowl nut (it’s plastic). If the engine runs rough after install, clean the main jet with compressed air.
• Returns: Seller is generic; returns may be fussy. Test fit before fully assembling.

Should You Buy It

Yes, if you have a Kohler SV-series engine with surging or no-start issues and want a budget fix. It’s a solid value for DIYers—most installs work right out of the box. Avoid if you need OEM reliability for commercial use or if your engine is a non-SV Kohler model.
