32-853-08 Carburetor Replacement For Kohler Motor Courage SV710 SV715 SV720 SV725 SV730 SV735 SV740 SV810 SV820 SV830 SV840 22HP-27HP Engine

What It Is

This is a complete aftermarket carburetor replacement for Kohler Courage SV-series engines (SV710 through SV840) used in 22–27 HP riding mowers, zero-turn mowers, and tractors. It controls the fuel-air mixture entering the engine for starting, idling, and full-throttle operation.

Fitment & Compatibility

Before buying, verify your engine’s exact model number (stamped on the engine shroud or valve cover). This carburetor fits Kohler Courage SV710, SV715, SV720, SV725, SV730, SV735, SV740, SV810, SV820, SV830, and SV840 engines only—not the older Command or Courage single-cylinder models. It replaces OEM part numbers 32-853-08, 32-853-09, 32-853-10, and 32-853-11. Measure the mounting bolt spacing (center-to-center) at roughly 3.25 inches and the fuel inlet tube diameter (about 0.25 inch) to confirm physical fit. This is an aftermarket part; it may require minor adjustment of the idle mixture screw and throttle linkage to match your specific mower deck or chassis.

Key Things to Know

• Quality variance: Aftermarket carburetors often work well but may have slightly different jetting or gasket thickness than OEM. Expect to clean out any machining debris before installation.
• Installation difficulty: Moderate. You’ll need basic hand tools (screwdrivers, 10mm socket), and you must transfer the old choke and throttle linkage parts. Allow 45–90 minutes.
• Common gotchas: The included gaskets may be thin or misaligned—use a thin layer of gasket sealant or reuse the OEM gasket if it’s in good shape. The fuel inlet fitting might need thread sealant to prevent air leaks.
• Tuning required: After installation, you’ll likely need to adjust the idle speed screw and the air-fuel mixture screw (typically 1.5 turns out as a starting point) for smooth operation.

Should You Buy It

Buy this if your Kohler Courage SV-series engine runs rough, stalls, or won’t start due to a clogged or failed carburetor, and you want a budget-friendly replacement that works reliably after basic setup. It’s not for those wanting a direct bolt-on with zero tuning or for engines outside the SV710–SV840 range.
