2. The mixture may be adjusted as follows:
A. At the fuel injector, disconnect the clevis end of the mixture control cable from the control arm.
Loosen the jam nut that secures the clevis end.
B. Adjust the linkage by rotating the clevis end on the cable to obtain 0.010 to 0.030 of an inch spring
back on the instrument panel stop when in full rich position.
C. Reconnect the clevis end to the control arm and safety.
3. Check security of cable casing attachments.
4. Pull the throttle and mixture levers in the cockpit full aft to ascertain that the idle screw contacts its
stop and the mixture control arm contacts its lean position. A mixture control lock is incorporated in the
quadrant cover which prevents the mixture control from being moved to the idle cutoff position inadvertently.
The lock must be depressed before the control can be moved completely aft. Ascertain that the lock operates
freely without any tendency to bind or hang up.
