clutch
Hi there. I think checking all parts to see if they fit correctly.
Start with the clutch collet. Does if fit in the back side of the flywheel. IF you put the collet on the motor and press the flywheel on the collet, it should stay on. IF it moves (falls off, the you need a new collet. IF you press and hold it on and can turn it and the motor doesn't turn over (flywheel slips) need to replace)
IF all holds, then add the lock nut. If the flywheel has been ground down where the nut fits, you might have bottomed the nut out. It will never fit.
A new flywheel is needed.
check to make sure after assembly, there is minimal movement of clutch bell.
Locktite should not be needed on lock nut. Maybe on screw at the end to
hold the clutch bell on.
