ENGINE CONTROLS
The throttle, mixture, and propeller controls are centrally
located on the instrument panel; the mixture and propeller
controls are vernier push-pull controls with center-button
locks that prevent
"creeping.
"
Depressing the lock button
in the knob overrides the vernier and allows movement
throughout the full control range. Rotating the vernier knob
clockwise increases the setting; counterclockwise rotation
decreases the setting.
The push-pull throttle control reg-
ulates manifold pressure. Pushing the control forward
increases manifold pressure. Turning the friction lock
holds throttle position.

The hexagon- shaped push-pull control between the throttle
and propeller control regulates the engine fuel-air ratio
(mkture). Precise mixture settings are established with
the mixture control vernier while observing the EGT gage
on the pilot's panel. The propeller control regulates the
propeller governor which in turn controls engine
RPM.
Bushing the propeller con-
trol forward increases RPM
(low pitch), and pulling the
cont~;.ol aft decreases RPM
(high pitch). Fine pitch
changes are made by turn-
ing the knob to increase or
decrease RPM.
