I have read just about everything I can find on this subject, including what you have written here and in previous posts.
So tell me, given that I only have an EGT and CHT in the Bo but generally fly at 2300/full throttle at A080 to A100 (maybe 65% power at best from the IO520), why would I not just lean until it runs rough then richen (?) it just enough for smooth running?
Cheers
