No, it does have a little backfiring in the carb but just a spit or two and it feels like its only hitting on 4 or 5 cyls. Shut it off one night next morning would only turn over no starting after putting the items in it, it will start and run but just misses out.Before I tuned it it backfired real bad and wouldn't start
