Guys (and girls) - I'm going to be a new Mooney owner in the next few months... just gotta find exactly the right one to pull the trigger. I've read a lot on what to look for, but I'm still wondering about the significance of the compression values. I know basically what they are (compression in each cylinder), but what is that telling me about the health of the engine? What if I see an aircraft that has about 1000 hrs SMOH and it's 71, 75, 78, 76? Does that 71 mean the engine's not healthy? Something's about to get expensive?
Thanks for your advice and expertice.
