Yesterday at 14,500 ft. 0-360, 17 inches of manifold and 2550 RPM, my number one cylinder required 1/2 gph more fuel flow to keep it at 380 degrees or less and EGT was 150 degrees hotter. I was at altitude for over two hours. In addition my volts were running 13.8 to 14.1. The voltage alarm is set for 13.8, for low. Are these normal occurrences, do I need to check exhaust and intake gaskets and maybe alternator belt. The belt is 7 years old 750:00 hours, but looked good in March at the condition inspection.
Thanks
