Although apparently not usually part of a pre-buy, may I suggest you
ask the inspector the check the run-out of each engine?

I had an 'incident' with my BC-12D which caused the A&P to check the
engine run-out and it was out of limits, which required that we open
the engine and look around. Turned out the flange/hub was not exactly
perpendicular to the shaft, and since I'm running a wooden prop and it
was in fine shape, the thought was something happened long ago and
went unnoticed until now. - Mike
