Hi all, I found one we're pretty interested in, the only concern with this one is that the last major overhaul was in 1989. Would that be a big cause for concern? There was a top overhaul in 2017 and compressions are in the high 70s.. would that alleviate some of the concern with a 1989 overhaul? It has 727 hours smoh. Thanks for all of your help!
