I posted this on the red board too, but I'm concerned and am looking for advise anywhere I might get it. Thanks
A review of my engine analyzer data after my first post annual flight shows an anomoly. Cylinder 1 CHT has always been lowest (or tied with #2 for lowest) and #1 EGT has always been highest by 10 or 20 dF. On this flight, however, #1 CHT was highest - 390 dF - and its EGT was lowest. It stayed like this until I went to low power settings for landing at which point the #1 CHT and EGT went back to their "normal" relationship to the other 3.
This has been a very sweet running high mid-time engine ~1500 hrs, since I got the airplane in July of last year. I'd welcome any interpretation of this situation and can provide more data if that would be helpful.
