Ok still confused. Bare with me thru this weak explanation of what's happening. The chain feels like its on the gear. If I hand crank it forward, it moves the chain but it doesn't make any sound. For instance if I move it backwards it makes that cranking sound like its trying to start. Also, if I pull on it in the forward direction hard enough it will skip up one link at a time? Could it have to so with the tensioner.
