One New Aftermarket Replacement Welch Plug Fits Briggs & Fits Stratton Small Engines
This carburetor welch plug (also called a soft plug or expansion plug) seals internal passages in the carburetor body left over from machining. Welch plugs are small, disc-shaped metal plugs pressed firmly into place to prevent fuel and air leaks, maintain proper fuel mixture, and ensure consistent engine performance. Replacing a damaged or leaking welch plug is a standard step in any carburetor rebuild on Fits Briggs & Fits Stratton small engines used in lawn mowers, generators, pressure washers, and other outdoor power equipment.
Compatible With
Fits Briggs & Fits Stratton: Small engines equipped with carburetors using welch plug style seals. Verify your engine model number before ordering to confirm fitment - multiple welch plug sizes are used across the Fits Briggs & Fits Stratton engine lineup.
