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.

Thanks for the links!

I suspect the valves need adjusted and the timing may be off. I did have it started though(well my neighbor did when I was towing it behind my wheeler - but he kept accidentally letting go of the clutch while in gear and couldn't keep it running) and it seemed to revv up ok.

But now with the manuals I will have a little more guidance in getting the valves and timing set then I can go from there.

      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      My 1992 TRX00 recently stopped firing.  I understand this is a common problem. I have ordered an aftermarket CDI unit.    TJ
