Jim Zuege’s 3.0L Corvair – w/CMP



Here is another engine that ran flawlessly on the stand at the Zenith Open House, just two days ago. Jim did a very nice job putting together his 3,000 cc Corvair. It too only 2 seconds of cranking to go from collection of parts which had never run, to a living breathing motor on my test stand. I have seen this more than 500 times, but it never gets old. Witnessing another person’s personal moment of victory never does.



Jim is not a natural ham. I took about 15 tries to get this really good CMP. Most readers might think these moments should be more focused on careful engine monitoring, but truth be told, the engines do their break in with boring regularity and little supervision. The CMP is just a ritual used to pass the time on a break in run.




About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    Yes, it’s boring to watch an engine be pre-oiled and run for break-in. It’s a mark of how well Corvairs run, because they start easily and run so smoothly. At least, the silly Captain Morgan pose ends up being a fun tradition.

    I drink rum, and Captain Morgan is not a favorite. My favorite is a rum that still had a hint of molasses in it that was made in Hawaii, but I salute everyone who’s earned the right to strike the pose while their engine runs.
