Briggs & Stratton P2200 PowerSmart Series 2200 Watt 111cc Inverter Generator MECH-FUEL Error Fix: Fuel System Problems

Fuel-related issues causing hard starting, rough running, or stalling. Inverter generators have very small carburetors with tiny jets that clog easily from stale fuel deposits. Drain old fuel and replace with fresh gasoline. Use fuel stabilizer in every tank. Before storing for more than 2 weeks, either run the carburetor dry (close fuel valve and run until engine dies) or treat the fuel with stabilizer. The fuel cap vent must be open during operation — some models have a cap vent lever. Check the fuel line and fuel filter for blockages. Ethanol-blended fuel (E10) is especially problematic in small engines.
