I experienced a few seconds of rough engine operation at 2560 RPM while flying at 9500ft. OAT was 29F.
I then watched the #2 cylinder EGT drop from approx 1400F to 1190F. I also watched the #2 CHT drop from 280F to 200F.
It stayed like this for about 30 minutes while I circled the airport at altitude. Eventually the CHT very gradually rose to 230F and EGT rose to 1200F.
I did check carb-heat and had the usual a small drop in RPM with no rise of the course of one minute.
The CHT returned to normal as I descended.
Thoughts?
