I am wondering,did you found out more about the machine? I just bought one too. My didn't have a belt, so I bought 15 3/8 belt, and it seems to be good, but I am not quite sure, how to put it on. I took the screw off the part on the motor where belt goes, but that part still doesn't come off. Does it supposed to come off or do I take off the hand wheel? My belt is not a stretch belt.
