      If your Maruyama Brush Cutter engine won't start, first ensure the STOP switch is in the on position. Also, check the fuel tank and fill it if empty. If the engine still doesn't start, press the primer bulb until fuel flows through the fuel return line. If the engine is flooded, use the warm engine starting procedure.
