use Tetra II?
is a function of fuel-air ratio. Tetra II allows you to adjust the
mixture properly by responding to exhaust gas temperature (EGT) readings
as they reflect fuel-air ratio.
and response settings are simple on the Tetra II expanded scale, which
covers 250° F in 25° increments.
At constant throttle
setting, a variation in mixture will cause the EGT to rise and fall --
with the peak EGT occurring when the fuel-air ratio is chemically correct.
recommend the EGT be used for continuous operation be set at least 25°F
below the peak EGT, preferably enriching the mixture.
power is attained by enriching the mixture for an EGT drop of 100°F
below the peak.
In this way, you choose
between fuel economy or maximum available power, or any intermediate condition
