Over my first 80 hours I've been chasing a relatively high #3 CHT. At ROP cruise, #3 generally tend to run about 20F higher than #4, and 30-40F higher than #1 and #2. Once OATs get above 75F or so, low 400's (400-410) on #3 is not unusual to see at 75% climb, and high 380s to low 390s is common if I'm running 75% or above at cruise. FWIW, #3 and #4 both come right down to match #1 and #2 if I run peak or LOP at 65% or less. I've been working at various baffle solutions but today during my condition inspection I pulled all the plugs and, as I guessed, the #3 plugs look significantly different than the others:
Is this an indication that my #3 is probably running leaner than all the others or simply that it is running hotter than the others? Anything else I can learn about my CHT symptoms simply from the visual condition of the plugs?
Thanks
