CARBURETOR
The carburetor has been preset at the
factory and adjustment should not be
necessary. However, minor adjustment
may be required to compensate for
differences in fuel, temperature, altitude or
load.
• The air filter must be assembled to the
carburetor when running engine.
• Best carburetor adjustment is obtained
when fuel tank is 1/4 full.
• In order for the engine to run, the
operator presence control bar must be
held in the operating position. There-
fore, and assistant will be required to
hold the control bar in the operating
position when making final adjustment
to the carburetor.
See the adjustment section of your engine
manual for further instructions.

Do not attempt to increase engine speed
as it may result in personal injury. If you
believe the engine is running too fast or
too slow, take your lawn mower to an
authorized engine service center for repair
and adjustment.

replace the throttle control, see the
adjustment section of your engine manual.
