Ive got an 02 summit 800 and im not getting any spark. one of my pull starts recently blew to peices while running, so i got a new one put it back together sled seemingly runs great. I take it to quartz sled runs great all day till about 3:30 then nothing. Ive tried grounding the plugs and found that theres no spark. Im thinking its the stator or possibly the voltage regulator?!?!? Im wondering if theres a way to check them before running to the store? Ive also read that peices from the starters can get caught up on the stator, is this possible? I made sure everything was clean before replacing the starter.
