Set spark plug gap at .020 inch (.5 mm)
(Fig. 18).

Throttle Cable
Throttle control adjustment may be required if engine

control cable is installed, throttle must be adjusted.
1.
Stop engine and pull wire off spark plug (Fig. 8).
2.
Loosen cable clamp screw until throttle cable
slides (Fig. 19).
3.
Move governor control lever, throttle cable and
casing in direction of arrow as far as possible

4.
Move throttle control to
(FAST) position.
5.
Tighten cable clamp screw to lock adjustment in

Self-propelled Cable
If mower does not self-propel or has a tendency to
creep forward when traction is not engaged, adjust
wheel drive control knob on rear of gear box
(Fig. 20).
1.
Rotate control knob clockwise 1/2 turn if mower
does not self-propel. If mower creeps forward,
rotate knob 1/2 turn counterclockwise to loosen
belt.
2.
Adjustment is correct when:
•
mower does not creep forward when traction is
disengaged
•
control bar is at a comfortable operating distance
from the handle for operator’s hand when
disengaging and engaging the self-propelled
drive.
Note:
Do not overadjust cable. Cable should
be just tight enough to make wheels
turn when control bar is at a distance
from the handle that is comfortable for
operator’s hand. Overadjusting may
require excessive operator effort to
engage or disengage self-propelled
drive.
