I cut out my pea shooter yesterday, I drove it for about 3 hours. Then today I drove it about 2 hours,then it started to backfire. Then It got worse. now it wont run. Do I need a jet kit? Is it trash in the carb? To clear things up about the pea shooter, I cut the screen out , then I cut the small pipe out of the exhaust tip. Please help me, :evil: I am upset. :evil:
