As far as the tension, Yes I have it where it is suppose to be and it seems to be comparable to the tension it was when the deck was running without an issue.
Watching the Video myself it seems as only the one side is really the one bouncing. That is the side the little guide arm was sticking up on, which makes me think that maybe that is the issue although, I believe the reason it broke off was that the chatter allowed the belt to get on the wrong side of it which caused it to snap.
