Ok here's the story...had a bad stator...switched it out with a spare and got it running. If I let it sit over night would have to put a little gas in the cylinders to get it going then after that would be ok...yes it had old gas in the tank. Let it sit for a couple days...went and got fresh gas to put it out on the road for sale and no spark again. Found a ground wire not hooked up...hooked it up and still nothing. I have both stators out and on the bench...is there some kind of test i can do to see if they are truely bad? I am no electrician but can do a little testing. Not sure what the specs may be for this sled either...thanks for any help...yes it has a new battery...thanks again

had a 93 700 efi wildcat that had spark issues. went to local dealer for ohm/resistance readings for the stator. just had them print out electrical diagram and what the specs were to read about. ended up being bad voltage sensor, which was located behind stator. mine had efi and battery, not sure if will help you any but maybe common problem. your efi box flash codes?
