take the belt off and check the spindle bearings for roughness or a bent spindle also check and make sure your belt guides are in place and that the belt aint on the outside of the guides can you drive the mower around with out the blades engaged if no then it could be a seat switch killing the engine when you turn them on

Backfiring bad? This indicates that one of the valves are open during combustion and the expanding gasses are escaping through the open valve. So, is it intake or exhaust?
I would start by checking the flywheel key to see if it is sheared. The best way to check is to pull the flywheel and visually inspect the key because if the key is even slightly sheared the engine could backfire.
