Carburetor Kit Replacement for Kohler K241 K301 Replace 47-853-23-S Carb 47-559-11-S Fuel Pump Cast Iron 10 HP 12 HP

What It Is

This carburetor kit replaces the OEM carb and fuel pump assembly for Kohler K241 and K301 cast iron engines—commonly found on older riding mowers, garden tractors, and industrial equipment in the 10–12 HP range.

Fitment & Compatibility

Before buying, confirm your engine model (K241 or K301) and that it uses the 47-853-23-S carburetor and 47-559-11-S fuel pump. These engines are typically on brands like Cub Cadet, John Deere, and Simplicity. Check the mounting bolt pattern (two-bolt flange) and fuel line diameter (usually 1/4-inch). Measure the carburetor throat opening—most are 1-inch. This kit is not for newer Kohler Courage or Command series engines.

Key Things to Know

• Quality variance: Aftermarket kits often use slightly softer gaskets than OEM. Replace all gaskets and seals included; reuse only if originals are in perfect condition.
• Installation difficulty: Moderate. You’ll need basic hand tools, carb cleaner, and a torque wrench (fuel bowl bolts to 25–35 in-lbs). Expect 30–60 minutes.
• Common gotcha: The fuel pump diaphragm may need adjustment. If the engine surges or stalls, check the pump lever alignment with the cam lobe.
• Jetting: Most kits come pre-jetted for sea level. For high altitudes (above 5,000 ft), you may need a smaller main jet (sold separately).

Should You Buy It

Buy this if you have a Kohler K241 or K301 engine with a failing carburetor or fuel pump and want a budget-friendly replacement. It’s a solid value for DIYers, but skip it if you need exact OEM fitment or have a newer, non-cast-iron Kohler engine.
