Carburetor for Kohler 22 23 24 25 26 27 HP Courage Series SV720 SV725 SV710 SV715 SV730 SV735 SV740 SV810 SV820 SV830 SV840 Engines with Air Filter Tune Up Kits

What It Is

This is a complete carburetor replacement kit for Kohler Courage Series V-twin engines (SV720 through SV840) used in residential zero-turn mowers, lawn tractors, and garden tractors. It includes the carburetor plus an air filter and spark plugs for a full tune-up.

Fitment & Compatibility

• Engine models: Kohler Courage SV720, SV725, SV730, SV735, SV740, SV810, SV820, SV830, SV840 (22–27 HP).
• Check your engine spec number (stamped on valve cover or shroud)—this fits most, but variations in fuel line diameter (1/4" vs 5/16") and gasket shape exist.
• Machine brands: Commonly fits Craftsman, Husqvarna, John Deere, Cub Cadet, Troy-Bilt, and others using these engines. Confirm your mower’s engine model, not the deck size.
• OEM vs aftermarket: This is aftermarket. OEM Kohler carburetors (part #24-853-22-S) cost 2-3x more. Check if your engine has a fuel solenoid (this kit may not include one; reuse your old solenoid if needed).

Key Things to Know

• Quality consistency: Aftermarket carburetors vary; some users report needing to adjust the idle mixture screw or clean debris from the bowl. Expect minor tuning.
• Installation difficulty: Moderate. Requires removing the old carb, swapping gaskets, and reconnecting fuel lines and throttle linkage. Have a small screwdriver set and carb cleaner handy.
• Common gotcha: The air filter may not match every housing perfectly—measure your existing filter (length and width) before assuming fit. Spark plugs are generic; verify gap (typically 0.030") against your engine spec.
• Tune-up included: Kit often comes with two spark plugs, air filter, fuel filter, and carb—good value if you need all items. But if you only need the carb, the extra parts may be lower quality than OEM.

Should You Buy It

Buy this if you have a Kohler Courage engine with rough idle, surging, or hard starting and want a budget-friendly complete refresh. It’s ideal for DIYers comfortable with basic carb tuning and willing to adjust for aftermarket fit. Skip it if you need exact OEM specs, have a fuel solenoid-equipped engine, or prefer a plug-and-play replacement without potential tweaking.
