Note: Always change both belts at the same time, even if only one is worn.
Worn pulleys can cause noise.
Crank the starter motor with the stop control pulled out. Starter motor speed should then be normal. Listen for any noise.

The earth strap must be securely fixed in position and the control points on the starter motor and chassis must not be corroded.
