Spark Plug
Disconnect the spark plug wire and re-
move the spark plug.
Check the condition of the plug.
• A brownish tip reflects ideal condi-
tions. (Carburetor adjustments, spark
plug heat range,
etc.~
are correct}.
• A black insulator tip indicates foul-
ing caused by : carburetor idle speed
mixture and
I
or high speed mixture
too rich, incorrect fuel mixture ratio,
wrong type of spark plug (heat range),
or excessive idling.
• A light grey insulator tip indicates a
lean mixture caused by : carburetor
high speed mixture adjusted too lean,
wrong spark plug heat range, incor-
rect fuel mixture ratio, or a leaking
sea I or gasket.

If necessary add distilled water. Battery
connections must also be free of cor-
rosion. If cleaning is necessary remove
corrosion using a stiff brush then clean
with a solution of baking soda and water.
Rinse and dry well.
~CAUTION
: Do not allow clean-
... ing solution to enter battery. It
will destroy the chemical properties of
the electrolyte.
After reconnecting battery, coat battery
terminals and connectors with dielectric
grease (P/N 413 7017 00} to prevent
corrosion. Check that battery is well se-
cured and that battery vent tube is not
kinked or blocked.
