What It Is

This is a 12-piece carburetor kit designed to replace the carburetor assembly on Briggs & Stratton engines, specifically for Troy-Bilt TB110/TB200 mowers and other models using 163cc engines. It includes the carburetor, gaskets, fuel lines, and filters to restore fuel delivery and engine performance.

Fitment & Compatibility

• Engine models: Fits Briggs & Stratton 103M02, 09P702, 9P702, 550EX, 625EX, 675EX, 725, lc121p, and 163cc engines.
• OEM cross-references: Replaces Briggs & Stratton part numbers 594057, 592361, 594529, 799584, and 594058.
• Mower compatibility: Works with Troy-Bilt TB110, TB200, and similar push mowers with the listed engines.
• What to check before buying: Verify your engine model number (stamped on the valve cover or blower housing) and confirm it matches one of the listed numbers. Measure the carburetor mounting bolt spacing (typically 2.5 inches center-to-center) and fuel inlet size (usually 1/4-inch). This is an aftermarket kit, not OEM—check that gasket shapes match your old carburetor exactly.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (screwdriver, pliers, socket set) and about 30–60 minutes. Watch a video guide for your specific engine model if you’re new.
• Quality: Aftermarket, but reviews are strong (4.7/5). Some users report needing to adjust the float height or clean out debris from the new carburetor before installation.
• Common gotchas: The included fuel lines may be slightly longer than needed—trim to fit. Ensure the choke linkage aligns properly; misalignment can cause hard starting. Use a new air filter and fresh fuel to avoid repeat clogging.
• Kit contents: Carburetor, gaskets, fuel filter, fuel lines, and mounting hardware. Check all parts are present before starting.

Should You Buy It

If your Troy-Bilt or Briggs & Stratton mower is hard-starting, surging, or won’t run due to a clogged carburetor, this kit is a solid, cost-effective fix. It’s best for DIYers comfortable with basic engine work who want to avoid a $50+ OEM part. Don’t buy it if your engine model isn’t listed, or if you prefer OEM components for exact fit.
