Wow! I seem to be having the same problem with my 15.5 hp Briggs and Stratton OHV on a Craftsman riding mower. I did find that my Timing key was sheared and my flywheel was cracked around that timing key slot. I think the backfiring could have caused most of that. But I'm still stuck to trying to get it running again. Biggest piece of s**t mower I've ever bought.
