Recently, when Oscar, (owner of a Mooney,) and his son stopped in at Classic Aviation, he mentioned that he had been having some trouble with high CHT’s on takeoff and climb, (maybe even in the 420-450 degree range at times.)  Everything was fine in cruise.

So we talked about the normal things you would think of to reduce cylinder head temps… check the baffles and baffle seals, verify correct mag timing, verify a good ground connection between  the engine and airframe, verify correct fuel flow, etc.  Oscar indicated he had considered all those options.  He did say he thought maybe the fuel flow should be a little higher, but with a carbureted engine, full power fuel flow is not field adjustable.

So one question would be:  should he replace the carburetor, or send it out for bench testing?

This is what we’re talking about in today’s episode, and we’re looking for your ideas.

If you have any ideas for how Oscar can bring his CHT’s down (Lycoming O-360 engine,) please comment on this episode, send me an email, or leave a voice message here on the website.

In the next episode, we’ll be talking about a story Jeremy Zawodny sent me about his partial power loss after takeoff in his Glastar.  It’s definitely a story worth learning from!
