What It Is

This carburetor kit replaces the fuel metering assembly on Kohler Courage SV-series engines (SV710–SV840) ranging from 22 to 27 HP. It’s designed for residential and light commercial zero-turn mowers, tractors, and generators using these engines.

Fitment & Compatibility

• Engine families: Kohler Courage SV720, SV725, SV710, SV715, SV730, SV735, SV740, SV810, SV820, SV830, SV840.
• OEM part numbers: Replaces 32 853 12-S, 32-853-08, 32-853-06, 32-853-04, 32-853-08-S. Cross-check your engine’s spec number (stamped on the valve cover or blower housing) against these numbers.
• Physical check: Measure the mounting flange bolt spacing (typically 2.75” center-to-center) and verify the choke linkage style matches your original. Some Courage engines use a plastic vs. metal throttle shaft—confirm your old carb uses the same shaft diameter.
• Fuel line size: Inlet is 1/4″ barb. If your line is 5/16″, you’ll need an adapter or a different kit.

Key Things to Know

• Quality variance: This is an aftermarket kit. Many users report it works fine after a thorough cleaning, but a small percentage have gaskets that weep or float heights set too high out of the box. Plan to check and adjust the float level (typically 1-1/8″ from gasket surface).
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, disconnect throttle/governor linkages, and swap the carb. Expect 30–60 minutes. Keep a magnet tray for small screws.
• Common gotcha: The included gaskets may not match your intake manifold exactly. If they’re too thin or thick, reuse your OEM gasket if it’s in good shape. Also, the choke plate may not seat perfectly—verify full closure before reinstalling.
• No warranty support: Return window is short (typically 30 days). Test fit immediately and don’t discard your old carb until the new one runs.

Should You Buy It

This kit is a solid budget fix if your engine floods, won’t start, or runs lean/rich, and you’re comfortable with basic carb work. Skip it if you want OEM reliability or if your original carb has warped castings—replace the whole carb instead. For $28, it’s a worthwhile gamble for a quick repair on a non-critical mower.
