... CAUTION: If spark plug condi-
... tion is not ideal, contact your au-
thorized dealer.
Check spark plug gap using a wire
feeler gauge. Gap must be 0.5 mm
L020"L
Reinstall plugs and connect wires.
Battery
Check electrolyte level. Electrolyte
level must be at upper level line on
battery casing.
Spark Plugs
Open access door. Disconnect spark
plug wires and remove plugs. Check
condition of plugs.
• A brownish tip reflects ideal condi-
tions. (Correct carburetor adjust-
ment, spark plug heat range, etc.).
• A black insulator tip indicates foul-
ing caused by: carburetor idle speed
mixture and / or high speed mixture
too rich, incorrect fuel mixing 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,
incorrect fuel mixture ratio, or a
leaking seal or gasket.

If necessary add distilled water. Battery
connections must also be free of corro-
sion. 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 cleaning
.. solution to enter battery. It will
destroy the chemical properties
of the
electrolyte.
After reconnecting battery, coat bat-
tery terminals and connectors
with pe-
troleum jelly to prevent corrosion.
Check that battery is well secured and
that battery overflow tube is not
blocked or kinked.
A WARNING: Overflow tube must
... be free and open. A kinked or
bent tube will restrict ventilation and
create gas accumulation
that could re-
sult in an explosion. Avoid skin contact
with electrolyte.
.. CAUTION: Prior to charging the
.... battery, always remove it from
the vehicle to prevent electrolyte
spillage.
Suspension
Visually' inspect suspension springs.
Replace any weak or broken spring.
Tracks

bers are exposed or missing or defec-
tive inserts are noted, contact your
