What It Is

This is an aftermarket carburetor assembly designed for Kohler Courage single-cylinder engines in the 22–27 HP range (SV series). It includes a built-in fuel pump, replacing OEM part numbers 32-853-12-S, 32-853-08-S, 32-853-06-S, and 32-853-04-S. It’s intended for residential lawn tractors, zero-turn mowers, and other equipment using Kohler SV720–SV840 engines.

Fitment & Compatibility

• Engine models: Kohler Courage SV720, SV725, SV730, SV735, SV740, SV810, SV820, SV830, SV840 (22–27 HP). Verify your engine’s spec number (e.g., SV720-3040) on the engine shroud.
• Deck size is irrelevant – compatibility is engine-specific, not mower brand or deck width.
• OEM cross-reference: 32-853-12-S, 32-853-08-S, 32-853-06-S, 32-853-04-S. This aftermarket unit may not include gaskets, fuel line fittings, or mounting hardware – check your old carb to confirm what transfers.
• Measurement check: Measure the mounting bolt spacing (typically 2.25” center-to-center) and fuel inlet/outlet port diameters. If your engine uses a separate fuel pump, this carb’s integrated pump will replace it – ensure fuel line routing matches.

Key Things to Know

• Quality variance: Aftermarket carburetors at this price point often have inconsistent jetting. Expect to adjust the idle mixture screw and possibly clean out machining debris before installation.
• Installation difficulty: Moderate – requires removing the old carb, transferring the throttle/choke linkage, and priming the fuel pump. Have a small screwdriver set and thread sealant for the fuel bowl screw ready.
• Fuel pump priming: The built-in pump needs the engine to crank to work. If the engine won’t start after installation, manually fill the carb bowl through the vent tube to prime it.
• Return policy check: With a 3.8 rating and only 9 reviews, verify the seller’s return policy. Some aftermarket carbs fail within a season due to diaphragm or gasket issues.

Should You Buy It

This carb is a budget-friendly option if you’re comfortable with basic engine work and don’t mind tuning it yourself. It’s best for a mower that’s not worth the $80–120 OEM replacement cost. Skip it if you want bolt-and-go reliability, need exact OEM fitment, or your engine has a separate fuel pump mount that this integrated unit might interfere with.
