What It Is

This is a complete carburetor replacement kit for Craftsman lawn tractors with 14hp to 18hp engines (typically Briggs & Stratton single-cylinder). It includes the carburetor, air filter, and fuel filter, designed to restore fuel delivery and engine performance when the original carb clogs or fails.

Fitment & Compatibility

• Engine family: Fits Briggs & Stratton engines used in Craftsman tractors with 14hp, 15hp, 16hp, 17hp, 17.5hp, or 18hp ratings. Cross-reference your engine model number (stamped on valve cover or blower housing) with OEM part numbers 792358, 794572, 799727, 698620, 793224, 697190, or 697141.
• Check before buying: Measure the carburetor mounting flange bolt spacing (typically 2.5" or 3" center-to-center). Verify your air filter housing shape matches the included filter. Ensure the fuel line diameter (usually 5/16" or 1/4") matches the included filter barbs.
• Not compatible: Does not fit twin-cylinder engines, zero-turn mowers, or non-Craftsman brands without verifying engine model.

Key Things to Know

• Quality: Aftermarket kit, not OEM Briggs & Stratton. Some users report needing to adjust the idle mixture screw or clean out shipping debris before install.
• Installation difficulty: Moderate. Requires removing the old carb, transferring the throttle/governor linkage, and setting the float height. Plan 30-60 minutes.
• Common gotcha: The included gaskets may be slightly thinner than OEM. Use a small amount of gasket sealant on the intake manifold gasket to prevent vacuum leaks.
• Includes: Carburetor, air filter, fuel filter, gaskets, and mounting hardware. No spark plug included despite the category.

Should You Buy It

If your Craftsman tractor with a 14-18hp Briggs engine is hard-starting, surging, or won’t run on old gas, this kit is a cost-effective fix. It’s best for DIYers comfortable with basic carb work—skip it if you want OEM-grade durability or need a spark plug.
