The 420 engine is basically a Deutz copy, and they will run backwards if during a cold weather start the compression lever is operated at the wrong time of the engine rolling over, but as said, pull the decompression lever full up as if its was a cold weather start, pull the starter and try a little bit of leverage against the ring gear. I have had one that had a stuck pilot bearing also, and maybe this backfire did some damage to the clutch area? slim idea on that. but a better description of what the engine was doing at the time of backfire is needed, ie: rolling over, and the decompression was operated? was attempting to start[ puffing smoke], grinding noise heard, starter was noisy/operating is somewhat spurts of power. And when they backfire and run a lot of black smoke comes out of the air intake/exhaust, or any other leak it can find :) so the actual time/sequence is needed? a backfire as said could be a internal failure while it was running hope it helps
