When Engine Suddenly Stops
IMPORTANT: When the engine has suddenly stopped, allow the engine to decompress; then try to turn the
engine over by lightly pulling on the fan belt. If the engine turns easily without any abnormal resistance, the
cause of the trouble is usually lack of fuel or a bad nozzle.
