After my recent engine rebuild, I've had high CHTs (higher than normal) and have been trying to track down the problem. Turns out that my timing was advanced by about 1.5-2 degrees (~27 instead of 25) and shifting the timing made at least 20 degrees of CHT difference. Before, I couldn't run above about 2300 RPM without the temps going over 400, and now I can run full throttle without getting over 400.
Probably something a lot of folks already know, but it was a definite learning experience for me to find out that only a slight difference in timing could affect such a dramatic CHT difference.
