#1 and #2 high egt and cht

Check for an intake air leak. Particularly the carb to manifold socket for cracks.

After sleeping on this I believe the fuel filter has not been changed for years.  Does anyone have a recommendation for a replacement.  The plane was built in 2007 and I saw nothing in the logs about the filter ever being changed.

What filter does it have on it now?

Just saw this while looking through forum. 

IF you only had high EGT and power reduction on this very hot day, you were running very rich fuel during power strock. So, since most of  the fuel was wasted through EXGHUST instead of mechanical energy during power stock  you had reading of high EGT AND POWER REDUCTION. 

You have to check density altitude and probably need to change position of circlip to run lean or just fly when cooler or when density altitude is lower.
