Carburetor
WARNING: If any adjustments need to be
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of muffler, engine
and other surrounding heated surfaces.
• Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
• Refer to the separate engine manual, packed with
your unit, for carburetor adjustment information.
Drive Wheels
• The wheels may be adjusted for two different
methods of operation. Follow the steps below for
adjustment. See Figure 20.

One Wheel Driving
• On the right side of the unit, place klick pin in the
outside axle hole only. Do not place pin through
wheel hub. This position gives power drive to the
left wheel only, making the unit easier to maneuver.
Both Wheels Driving
• Rotate wheel assembly to align hole in the hub with
the inner hole on the axle shaft. Insert klick pin in
the hole. Outer axle shaft hole should be visible.
See Figure 20.
