Carburetor For Kohler CV730 S CV740 S 25HP 27HP Engine 24853102-S Tractor Carb with Air filter Tune-Up kit

What It Is

This is a complete carburetor replacement kit for Kohler Command PRO CV730-S and CV740-S engines (25–27 HP), commonly found on zero-turn mowers, garden tractors, and commercial mowers. It includes the carburetor, air filter, fuel filter, gaskets, and spark plug—everything needed for a full tune-up in one package.

Fitment & Compatibility

Before buying, confirm your engine model: Kohler CV730-S (25 HP) or CV740-S (27 HP). Check the engine ID tag (usually on the blower housing) for the exact spec number—this carb fits most but not all variants. It replaces OEM part 24853102-S. Measure your carburetor mounting bolt spacing (standard 2.5" center-to-center) and compare to the included gasket. This kit is aftermarket, not genuine Kohler, so it may not fit engines with electronic fuel shut-off solenoids or non-standard throttle linkages. Verify your fuel line diameter (typically 1/4" or 5/16")—the included filter may need an adapter.

Key Things to Know

• Quality varies – Some users report needing to adjust the idle mixture screw (usually 1.5 turns out) or replace the included spark plug with a genuine NGK BPR4ES for better reliability.
• Installation difficulty – Moderate. Expect to remove the air filter housing, fuel line, and throttle cable. A carburetor gasket kit and basic hand tools (screwdrivers, 10mm/13mm sockets) are required.
• Common gotcha – The aftermarket carb may have slightly different jetting than OEM, causing lean or rich running. Clean the old fuel tank and lines thoroughly before installing to avoid debris clogging the new carb.
• Not for all CV730/740 – Does not fit engines with a fixed-jet carburetor or those requiring a different mounting flange pattern (rare, but check your old carb’s shape).

Should You Buy It

Buy this if you need a budget-friendly, all-in-one tune-up for a CV730 or CV740 engine and are comfortable with minor adjustments (idle screw, linkage alignment). Skip it if you want a perfect drop-in fit with no tweaking—genuine Kohler parts cost 2–3x more but avoid potential quality issues. Ideal for DIYers maintaining a residential or light-commercial mower.
