So I mounted up my engine and ran the chain, had to put a tensioner on top so the chain would clear the top part of the frame. Ran her around the block and she did fine. The next day I went halfway down the block and the engine got pulled back by a half an inch or so, mounts and all. The chain went loose and I had to pedal her back down the street. It sucks cause it pulled the muffler to where it touches the front frame, now I'm going to have to figure out how to get the engine pushed forward again and get it to stay. Red have you had this problem yet?
