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 engine can produce either the best 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
