Is it common, semi-common, or insane that I blew a spark plug out of the cylinder? It looks like the guy I purchased my cobra from didn't exactly replace the plugs and wires properly and now I'm in trouble. The threads on the head are stripped, but the plugs threads aren't beat up at all. Just curious if this has happened to anyone else. Also, I don't suppose anyone would have a rough ballpark on what the cost of repair would be? Thanks.
