So the latest in a very long series of problems with my ped occured last night, and, to tell the truth, is a bit bizarre. So it's been having spark problems, and I've been doing my best to figure out what they are. Last night I finally got so frustrated I got around to changing the points, and after I changed them, it sparked right up. I then set the timing with a pencil with mm markings in it, but I set it very inaccurately, but I thought at the time that it was more accurate than I think it is now. anyway, I put the plug back in and tried to start it and it wouldn't start, but it would make this horrible squeeking noise around the muffler, so Itook of the muffler and it still wouldn't start, but it would, however, backfire and shoot a HUGE foot long blue flame out of the back of my exhaust. I'm not joking. I have no idea; but if anyone else does, please let me know. thanks.
