ive checked everything,added 2 shims to each bolt and clucthes are fully closed"meaning sheaves touch on the inside".....now when i put my belt on the clucthes wont close all the way,ive blurped the gas and let it coast to a stop and belt still sits down in secondary...ive grinded off the casting on the inside also,clucthes close when belt is off,stay open when belt is on....please some info....
