  1. Giving a counternut and the adjusting screw on the opening party, expose a backlash between a screw head and the throttle lever on the party №1 (illustrations see).
  2. Gradually tightening the screw, result it in position in which it starts to concern the lever.

Do not draw the screw. Then turn out the screw on a turn quarter. Also fix it in this position by a counternut.

  1. Repeat the described adjustment for the screw on the opening party.

The adjusting screw from position of contacts with the lever should be tightened on 1/23/4 a turn.
