I looked through a lot of the posts about no spark and not starting on the 90 cc Polaris quads and it looks like the stator is usually the problem. My son was riding through some puddles and eventually the quad stopped and would not start. Will turn over, just won't fire. So we parked it for a couple of weeks, I charged the battery, and pulled the plug to check for spark. It sparked once and that was it. Now it has no spark. I have checked all the usual conncections and they appear fine. Any guesses as to why it would spark once and then not again? It did not spark before I charged the battery at all, but just once after? This 90 has always been very hard to start. It takes a lot of cranking and sometimes I have to remove the air cleaner boot to choke it off a little more to get it to fire in any weather. Are there any electrical or carb mods that would help it fire right up? I have already converted the choke to a manual style from the later models and did away with the electric one. Any help would be appreciated. Thanks!
