Caution to those pondering a zero-choke re-man by this company.

My O-470J lasted 200 hours before four cylinders showed mid-fifties
compression with Blackstone labs reporting symptoms of excessive ring
wear.

Even after admitting, view phone, that the test-stand results were
abnormal, Ney himself refused to stand behind the engine, on the
grounds that the plane's former owner -- his customer -- made him use
reconditioned cylinders.


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.
