Re: clutch prob
Take off the big cover on the right side of the engine.
You will see a 'star' shaped nut in the center of the clutch... take out the tiny set-screw that keeps it from turning, then tighten the 'star' nut 2-'clicks', NOT 2 TURNS!!! Then test to see if the clutch is grabbing. Keep tightening it one 'click' at a time until it works good.
Once it works, put the set screw back in & the cover back on...
