Briggs & Stratton Briggs & Stratton 2000 PSI 1.2 GPM Electric Pressure Washer MECH-ENGINE-SURGE Error Fix: Engine Surging (Gas Models)

Error code MECH-ENGINE-SURGE on the Briggs & Stratton Briggs & Stratton 2000 PSI 1.2 GPM Electric Pressure Washer means: Engine Surging (Gas Models). The gas engine repeatedly revs up and down instead of running at a steady speed. The most common cause is a carburetor issue — stale fuel deposits clog the jets and passages. Clean or rebuild the carburetor. Check the air filter for heavy dirt buildup. Inspect the governor linkage for binding, bent rods, or broken springs. A vacuum leak at the intake manifold gasket can also cause surging. The fuel cap vent must allow air into the tank — a clogged vent creates a vacuum that starves the engine. Try loosening the fuel cap while the engine runs — if surging stops, the cap vent is blocked.
