I am not sure if it was the reason why my motor crapped out but I know it didnt help either . When I was tightening the inner clutch I was pushing my back wheel counter clockwise instead of clockwise now that I tighened my inner clutch the rite way now it is too tight I think . If some that sees this can tell me why my engine now really and trully sounds like a weed eater cuz I am stumpt and it seems harder to start .
