Just incase GranpaJ you still are wondering. The small right side gear is on the right end of the crankshaft. The spinning generator magnet is on the left end of the crankshaft. The timing is controled by the magnet. There is a key slot in the magnet that keeps it positioned for the timing. Check that Key if the timing seems off. The gears on the right side just drive the clutch shaft, they have no affect on the timing. How old is your motor? Those gears seldom fail.
