Sooo, I bought a 2001 arctic cat 250, had no compression, so I seated the valves, new piston, and complete rebuild, got it all together and fired up and ran perfect, then after a couple days, all the sudden started spun half a turn, then little pause, then did it again etc! Figured it was the starter, put a new one on a month later after opening up crankcase yo make sure all was good, and fired right up, drove it for 5 minutes, then all the sudden it started to die, forced me to a some what rather quick stop. Rolled it back to shed, and got it to fire up again, then I shut it off, and never was right from there. I’ve added new solenoid, ignition coil, starter, piston, took the head apart three times now and no binding of any kind, has amazing compression! And also has a very good battery! I’m soo lost please help!!

 

Somebody also mention the coil around the flywheel could be bad, maybe messing with the starter, I’ve got no clue after banging my head over this
