Carburetor Carb for Kohler 8HP K90 K91 K181 K141 K160 K161 Motor Engine 46 853 01-S/46 053 03-S with Gasket 231847-S Engine Air Filter

What It Is

This is a complete replacement carburetor assembly for Kohler K-series single-cylinder engines, including the K90, K91, K181, K141, K160, and K161 models, typically used in walk-behind mowers, garden tractors, and small industrial equipment. It also includes a gasket and air filter.

Fitment & Compatibility

• Engine models: Kohler K90, K91, K181, K141, K160, K161 (all 8HP variants). Verify your engine’s model number stamped on the blower housing or valve cover.
• OEM reference: Replaces Kohler part numbers 46 853 01-S and 46 053 03-S.
• Includes: Carburetor, mounting gasket, and a rectangular foam air filter (fits Kohler 231847-S). No fuel line or primer bulb included.
• Not compatible with Kohler Courage, Command, or other series engines. Measure your mounting bolt spacing (typically 2.5” center-to-center) and intake port size (about 1” diameter) before ordering.

Key Things to Know

• Quality: Aftermarket carburetor at a budget price. Expect zinc alloy body, plastic float, and basic brass jets. Tuning may be needed out of the box (idle screw, mixture screw).
• Installation difficulty: Moderate. Requires removing old carb, cleaning intake gasket surface, and adjusting throttle/choke linkage. A small screwdriver set and 10mm wrench are needed.
• Common gotchas: The included gasket may be thinner than OEM; use a thin layer of gas-resistant sealant if you see air leaks. The air filter is foam only—no pre-filter or paper element—so it’s less effective in dusty conditions.
• Performance: Works well for mowing and light use, but may not hold tune as well as an OEM carb under heavy load or high heat.

Should You Buy It

Buy this if your Kohler K-series engine has a worn, clogged, or non-rebuildable carburetor and you want a quick, low-cost fix for a mower or tractor that sees occasional use. Skip it for commercial or daily-use machines—spend more on an OEM or high-quality aftermarket unit for better durability and tuning stability.
