engine can’t start –malfunctions of cylinder head or assembly
–carburetion without oil valve will effect the capability of the engine.
–tank without fuel Those problems can be checked by testing of air
–jam of oil filter pressure or leaking or by detecting pole of
–jam of oil tube phonating position or stethoscope.
–jam of tank cover assembly hole –if idle speed of engine is in bad condition, check
–error of oil level if the blowhole of crankcase is smoking, if so
–floater gets stuck check if the ring of piston gets stuck.
