BRAKE ADJUSTMENT
(See Figure 17)
The brake is located by the right rear wheel inside
the frame. The brake has been set at the factory to
the proper clearance. During normal operation of this
machine, the brakes are subject to wear and will
require periodic examination and adjustment.
WARNING:
Do not have the engine
running when you adjust the brake.
To adjust the brake, adjust the nut so the brake
starts to engage when the brake lever is 1/4" to 5/
16" away from the axle housing.

CARBURETOR ADJUSTMENTS
WARNING:
If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), disengage all

moving parts. Be careful of heated

Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to separate engine manual
for carburetor adjustment information.
NOTE:
A dirty air cleaner will cause an engine to
run rough. Be certain air cleaner is clean and
attached to the carburetor before adjusting
carburetor.
