My Grandpa has a 2003 Can-Am Quest 500 he said he was riding it to the mail box and when he backed up to come back it popped and died. He then got it back to the house and when he tries to start the atv it sounds like it will not turn over fast enough. When I pull the plug out it sounds fine but when I put the plug back in it sounds like the compression release will not let it turn over fast enough. Please he needs help thanks
