Step 27
Move the throttle stick and trim to the closed
position. The carburetor should move to the
fully closed position.
If the servo is binding, you may need to
reduce the amount of travel mechanically.
Moving the clevis away from the center
on the carburetor arm, or the linkage
towards the center on the servo arm will
accomplish this.
If the carburetor is not closing, you need to
increase the amount of travel mechanically.
Moving the clevis toward the center
on the carburetor arm, or the linkage
away from the center on the servo arm will
accomplish this.

This is all done to allow for a full range of
operation of the carburetor using the radio.
If you must move the linkage, return to
Step 26 and start over the process of
adjusting the clevis.
Step 28
Move the trim lever up, but leave the stick down. The
carburetor should open about 1/16".
