I just bought another blaster last weekend, it ran fine then. Went to start it today and it barely ran and when it did it was backfiring.....any ideas? Real hard to start also.

Thanks

check the above mentioned and i always thought when the woodruff key on the flywheel breaks, it gets out of timing and backfires???
