Power
As the mixture is leaned, EGT rises to a peak temperature, and then drops
as the mixture is further leaned. Peak power occurs at a mixture using
more fuel than at peak EGT. Best economy occurs at peak EGT. Accurate
leaning yields optimal engine temperatures. By being able to precisely
adjust the mixture, your engines can produce either the highest fuel
economy or maximum power, whichever you choose.
A single EGT gauge merely gives you an average of each cylinder’s
temperature: some cylinders can be too rich, while others too lean.
Variations produced by differences in fuel distribution, ignition, and
compression will cause each cylinder to follow its own mixture and
