MAINTENANCE

CARBURETORS

Clean the terminals, the battery posts, and the
connectors with a solution of baking soda and
water. A wire brush or battery terminal tool can be
used to remove corrosion buildup. Rinse and
clean all surfaces.
WARNING
Keep battery connections clean, tight, and
insulated to prevent shorting or arcing,
which can cause an explosion. If the bat-
tery mounting system does not cover the
connections, install covers.
Install the battery. Connect the battery cables to
the battery. Always connect the positive (+) bat-
tery cable first. Tighten all connections securely.
Coat all connections with Triple-Guard grease and
insulate the electrical connections to prevent
shorts or spark arcing.

CARBURETORS

General

Inspect the carburetor bodies, linkages, fuel inlet,
and air silencer pipe for cracks and other damage.
Replace any damaged components
The air silencer pipe minimizes audible noise
related to air flow into the engine. It also collects
any fluid residue that migrates from the leaf plate
or the throttle body area. Periodically clean the air
silencer pipe to remove any accumulations.
