——When checking starter, you should clean carbon brush. Its surface should not have dust and calibrator,
and the brush can move freely in the carbon brush carrier. Change them if the brush and carrier are
damaged severely.
——Clean the commutator's surface with clean cloth. And engage the commutator if its surface is not
smooth and round. ——As assembling carbon brush, make sure the brush spring is pressed on the brush
correctly.
——Pay more attention to keep the wire bayonet clip clean. Make sure there's no oil fouling and water. Or
the voltage drop is too high, and the engine doesn't work.
