I never have. After 20 years of this a touch of the head after a flight gives me a good idea if it's to hot. One other thing before you do all that work. Fly it without the cowl. If the problem is still there you will know where to look. It is possible you have a bad bearing or a muffler baffle problem. These things would be last on the list of causes, but they do happen.

Thats a good suggestion.

I might be wrong, but I remember reading that your outlet area should be about 3 times the size of your inlet in order to have good airflow. Can anyone confirm this? Seems to make sense.
