Cylinder #2 and #4 are the hotter of the bunch.
On a relatively short 2nd flight today, I'd tried to make a good graph of my question.
Already warmed up from my previous flight, I climbed to about 3000, leveled off, and reduced power. Shortly there after I began leaning to peak EGT, then flew for a bit approx 50 degrees LOP. Then I enrichened to 75 ROP and flew around a bit.
You can see the the large CHT spread, approx 25 deg, during takeoff and ROP operations. LOP yields a significantly smaller, approx 10 deg, spread. If my baffling was poor on #2 and #4 wouldn't the spread stay the same?
By the way I don't think my baffling is poor, but I guess it could be.
My EGTs peak about the same time.
Already checked timing, senders, etc.
