That's one of the problems with buying a plane with a recent overhaul.
There isn't much of a chance that the seller did a good job of
overhauling the engine if he's just hours away from selling it. You'd
probably be better off buying a run-out airplane and getting the
overhaul done yourself. Also, you'd know that the engine was properly
broken in.

For purposes of avoiding one when buying, what's a "recent overhaul"?
100 hours? 200? 300? Put another way, after how many hours on an engine
can you tell that it's properly overhauld and broken in?
