My clutch engages in forward and reverse without issue while there is no load on teh skid. Like when its rear end is off the ground. But when teh rear end is on the ground and I jump on to go forward teh clutch engages but barely moves. Looking at the clutch I see the belt is still in the middle of the secondary and not rising back to the top. Anyone have any idea why a load on the skid would have this affect on the clutch? Better yet, anyone know what the problem is? It seems like I can go forward at first but if I try to go in reverse thats when it "sticks". My best guess would be a bad bearing. Any help?
