CARBURETOR ADJUSTMENTS
A
WARNING: Do not at any time make any adjust­
ment to lawn mower without first stopping
engine and disconnecting spark plug wire.
CUTTING HEIGHT ADJUSTMENT
Adjustment may be made by removing and moving axle bolts
to desired position. Cutting heights will be raised as axle bolts
are moved to a lower hole and lowered as axle bolts are
moved to a higher hole in the deck. All axle bolts must be
mounted in the same relative position. Cupped washers must
be assembled so that the cupped side of the washers are
against the deck. Refer to figure 6.
THROTTLE CONTROL ADJUSTMENT
If the throttle control requires adjustment or has been re­
placed, adjust the throttle control as follows.
1. Loosen (do not remove) the screw on the cable clamp
so that the cable will move freely under the clamp. See
figure 11.
2. Place the throttle control lever on the handle all the way
forward to START position.
3. Place the control lever on the engine in the full open posi­
tion by pushing it as far toward the outside (Briggs and
Stratton engine) or rear (Tecumseh engine) of the engine
as it will go. Tighten the screw on the cable clamp to
secure the cable in this position.
