So I've been having nothing but problems ever since I started working on this motor. From horrible instructions to everything vibrating apart it has been a big pain in my butt. Most of my issues have been with the nuts and bolts holding it in place were vibrating lose so I put thread locker on them all and JB weld on one that had stripped. Now it simply won't start at all. I thought it was an electrical problem caused by water getting into the capacitor but after replacing the capacitor it still won't start. Last time I got it running it ran for about 30 seconds with very weak throttle control before sputtering out. When I tried getting it to start after replacing the capacitor and all I got was one brief puff of smoke. I really don't want to take the whole thing off and replace it (not to mention I don't think I can take it off anymore) but at this point it seems like that is all I can do. Any suggestions as to what could be wrong?
