Ive got an 04 Blaster, and i can get it to start and run for only like 30 seconds then it backfires and dies, Ive pulled the carb and everything is clean and seems to be in good shape when it quit running I had it in the driveway warming up, it ran for about 10 minutes then died and hasnt run ever since.. it really confusing me I dont know what could be the issue.
