So my moped broke down today for the ten-millionth time, and the reason is because the drive belt would not stay on the track. It fell off, so I got off and put the belt back on, a block or two later it popped off again. The pulley is bent (see attachment), but it has always been bent, and I've never had any problems before. I don't want to order another pulley until I know I have to. I tried to straighten out the pulley, but I couldn't quite get it. Does anyone have any ideas? Thanks a lot.
