I bought this 250s from a friend, (along with a sweet ATC 70), but I am having all kinds of trouble getting this thing to run.
I rebuilt the carb, have strong spark and it is getting fuel. Seems to have great compression. I was able to push start it once or twice but my neighbor couldn't keep it running and trying to push start it destroyed the teeth of of both sprockets. Best I can do with the kickstart is to get a backfire when I drip a little gas in the cylinder.
Anybody have a good link to a service manual? I think the next thing to do would be to check the timing?? Not sure how as I don't see any inspection plugs anywhere on the cases.
Any input/help is greatly appreciated.
