Check and adjust linkage as follows, with engine stopped.
a. Before making adjustment, observe and note which hole in actuator lever (3) is used to
mount ball joint (4) . It does not necessarily have to be the same hole as shown in illustration
(Fig. 5), however, rod connection to fuel control lever (8) is always in the upper hole (the
hole nearest the fuel pump) .
b. Be sure levers (3 and 8) have not slipped on shafts. In IDLE position actuator lever (3)
should point forward and upward at an angle of 15 to 20 degrees. Speed control lever (8)
should point forward in a near horizontal position. If a lever has slipped, position correctly
and tighten securely.
c. Place both levers (3 and 8) in FULL IDLE position and attempt to connect ball joint (4) at
hole in lever (3) from which it was removed in step (a). If connection cannot be made,
loosen nuts, (5) and adjust effective length of rod so that connection may be made.
d. Manually operate actuator lever back and forth between FULL IDLE and FULL SPEED
positions. Speed control lever (8) should be moved freely through its full range between
FULL IDLE AND FULL SPEED. If adjustment is unsatisfactory, try another hole mounting in
ACTUATOR lever and readjust rod length.
e. Tighten all parts securely when adjustment is completed.
