One New Aftermarket Replacement Exhaust Valve Fits Briggs and Stratton Small Engines
This aftermarket replacement exhaust valve fits a wide range of Fits Briggs and Stratton (B&S) small engines used in lawn mowers, riding tractors, generators, pressure washers, and other outdoor power equipment. The exhaust valve seats in the cylinder head and opens to allow combustion gases to exit the cylinder on each exhaust stroke, maintaining proper engine compression and performance. Replacing a worn or burned exhaust valve restores compression and prevents hard starting, loss of power, and oil consumption.
