I just installed a new clutch in my cub. The petal is now jumping up and down at an idle in neutral. It didn't do this before. When I look thru the inspection hole while the tractor is idling it appears that the T.O.B is bouncing on the clutch fingers. When I installed the pressure plate all the fingers were even. any suggestions? I also may have installed the clutch plate backward. The long part of the spling is facing forward toward the flywheel, will this be a problem?
