Figure 73-3. Adjustment of Engine Controls
c. On aircraft equipped with air conditioning systems, a micro switch is located below the throttle
control which is set to actuate in full open position. With throttle control adjusted to obtain a
clearance of 0.010 to 0.030, adjust micro switch to actuate at this point also.
d. Reconnect clevis end to control arm and safety.
3. Check security of cable casing attachment.
4. Pull throttle and mixture levers in cockpit full aft to ensure that idle screw contacts its stop and mixture
control arm contacts its lean position. A mixture control lock is incorporated in quadrant cover which
prevents mixture control from being moved to idle cutoff position inadvertently. The lock must be
depressed before the control can be moved completely aft. Ensure that lock operates freely without any
tendency to bind or hang up.
