Cruise Leaning

Exhaust gas temperature (EGT) may be used as an aid for mixture
leaning in cruise flight. For "Best Power" use 75% power or less.
For "Best Economy" use 65% power or less. To adjust the mixture,
lean to establish the peak EGT as a reference point and then adjust
the mixture by the desired increment based on the following table:
Mixture Description Exhaust Gas Temperature
Best Power 75° F Rich Of Peak EGT
Best Economy 50° F Lean Of Peak EGT
Under some conditions, engine roughness may occur while operating
at best economy. If this occurs, enrich mixture as required to smooth
engine operation. Any change in altitude or Power Lever position will
require a recheck of EGT indication.
