H. Troubleshooting main drive belt
If the engine runs, but the drive unit will not engage,
this is usually related to the main drive belt. Without
removing the drive unit you can check and fix the
following:
1. Remove the two (2) 3/8" bolts holding the
belt cover to the body. Remove the one (1)
3/8" bolt holding the muffler bracket to the belt
cover. Check if belt tension by pinching belt
together. Belt should depress only 1/2".
2. Check to see if belts have come off of input
pulley or centrifugal clutch. If so, install belts
back on the pulley. Note: If belts come off
again they are probably worn or stretched
and need replacement.
