Idle Speed: Check and adjust idle speed as follows:
a. Operate the engine at 1500 to 1800 rpm until cylinder head temperatures are 250
°
F to
350
°
F and the oil temperature is 160
°
F to 180
°
F.
b. Reduce engine speed and stabilize it at 700
±
25 rpm.
c. Adjust the idle speed screw that is located on the aft side of the throttle lever until
contact is made with the throttle arm stop.
Full Power Performance: Check and adjust full power performance as follows:
a. Orient the aircraft so that it is pointed into the prevailing wind and run engine at 1500 to
1800 rpm until the oil temperature is 160
°
F to 180
°
F.
b. Using a handheld digital tachometer, adjust the propeller controls to 2600. With the
throttle in the full forward position, set the intake manifold pressure to the value shown in
Figure 23-5 (
±
0.5 In. Hg.) by adjusting the screw on the top of the controller.
Turning the screw clockwise decreases manifold pressure, and turning the screw
counterclockwise increases manifold pressure. One complete (360
°
) turn of the screw
changes the manifold pressure approximately 1.0 inch.
