I am in Michigan with OAT10-45 F. MP 22.5 and Prop 23. 3-5000 ft. I lean till just lean of peak at gph is about 11.0. Is this what others are seeing?
All good stuff if you have CS prop.
Many do not.

My take on that situation is MP to 23 or less and you can lean all day to hearts content, will never damage engine and plugs stay clean.
WOT all day applies only with CS prop. Did it all the time with Subby and MT prop worked great even at 2500'. WOT and 1900 rpm provided great efficiency.
Of course engine had knock sensor which Lycoming does not because it vibrates too much. And even if knock were sensed, it does not have brain to adjust timing.
Why does a fixed vs CS prop make any difference?
Thanks Todd - an engine management course sounds like what I need. Clearly over my head here.
