Hello all, I am in need of some assistance, Had some work done on the lathe, a Clausing MK3 model 100 12" and had some work done on it and after getting back the clutch handle won't hold engaged? It works its way back and releases. Not a good!!! Found the bushing on the clutch had wore out and had a new one made to spec. installed and works much better , But still will not hold or as I call it stay engaged?? ANY one have a clue as to what or how to adjust the clutch, THANKS!!!!!!
