Hopefully I haven't missed a previous thread on this...
I am consistently seeing CHT's around 15-20 degrees higher on the #2 cylinder during higher power settings. Also, both #1 and #2 run a bit higher than the others at most settings. Power setting around 50% and below result in more uniform temps but #2 is always the highest. On hot days the #2 CHT wants to get up around 385 during climbout.
I have checked baffling (including inter-cylinder), seals, etc and had done a couple of sessions with flashlight, mirror and RTV to get almost all the little gaps filled. My cowling is done per plans...nothing fancy there. Preflight and inflight mag checks indicate a healthy ignition system. I even checked to make sure my #2 CHT wasn't indicating +20 degrees at ambient temps. I'm curious if the temperature spread is a common thing among the 14's or if I have a elusive detail to pursue.
My plane has an IO-390, dual P-mags, and AFP FM-150 fuel injection system and I have about 35 hours on the plane. Again, I'm mainly curious if other operators are seeing something similar.
