OK, it has been a while and I have not yet found an airplane. So far, two failed pre-buy's (last one, a '65 Cherokee 180; my A&P found a leaking fuel tank, automotive air filter and alternator belt, fuel smell in cockpit, rudder in need of re-skining, etc. and seller refused to rectify).

I found a 1961 Cessna 172 for $43,600 with 1350 Hours TT and 60 SMOH to new limits with new cylinders on 0-300. Paint is new, but original interior and glass in good shape. Current owner, an A&P, bought it from an older pilot who let it sit in a hanger for 25 years and restored it. BUT, this owner admitted that he burned autofuel in it for about 5-10 hours of flight time total (over the last two years since overhaul) which contained methenol/ethanol. He does NOT have an autofuel STC (he said that such an STC is a lot of FAA bunk and unnecessary).

If I go after this airplane, what should my A&P look for in the way of alcohol damage to the engine and fuel system? Or should I pass it? I should also say that the owner is firm on his price and feels that it is no loss if he does not sell.
