I saw an ALH on craigslist that was said to have had gasoline run in it. Says it needs work. Not considering buying it at the moment but thought I'd ask what potential damage would such a blunder cause. Could it be as simple as flushing the fuel system with correct fuel and starting it up? Would there be other damage to engine such as to lifters or pistons/rods from an inevitable pre-detonation? Would there be damage to the fuel pump/seals from gasoline? I imagine this would be a fairly well documented issue.
