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.
