At low cruise settings, lean to get roughness (miss-firing
of the leanest cylinder) and then richen to smooth. You
have to do it very gently, just pressure on the mixture or
you'll over-shoot the settings. That is with a carb. If
you have fuel injection, it will run smooth until it quits,
follow the tables for fuel flow from the manual or use the
EGT.

For take-off above 3,000-5,000 feet density, you should lean
to get the proper mixture and max power.
