I had a similar problem when I first installed my ex-172 O320. Temps were
high and Bert Lalonde at Aerosport Power in Kamloops, BC, said the main jet
diameter would need to be enlarged. I mailed it to him and he did a good
job. No overheating problems since (with or without wheelpants)!

drills on a lathe) as soon as I can find one. One last question on that
topic. Is a "full-rich to first-cylinder-to lean EGT differential less than
150
degrees F.'" really a "recognized" way of detecting lean carburetor jetting?
The Lycoming representative said he had never heard of it but I found
references
to it during web searches and talking to two engine rebuilders.
