，直到控制杆达到要求的位置后重新紧固螺母；
•
by changing the radius of the adjustable control lever (5.19 Fig. 5A and 5D). To
do this, loosen the nut that fastens the ball joint of the thrust linkage (5.18 Fig.
5A, 5D), then move the ball joint along the slot on the lever (5.19 Fig. 5A, 5D)
until the ball joint reaches the required position, then tighten the nuts again;
