I've posted before about this but now have a little more info. The problem is sled does not run on mag side cylinder. Now I have 130 psi of compression, fuel is getting to the carburator and I put new jets in all three this fall. It has spark and I also took the head off and looked at the cylinder and looks good like its getting fuel and oil, no scarring. Is it possible that it could have enough spark to see but not enough to fire? I'm really lost as to what could be the cause. I had a friend ride it about 75 miles this year so far so if the cylinder wasn't getting fuel and oil would't the piston and rings be fried?
