BREATHER AND FUEL LINE
SPARK PLUGS
Inspect the breather and fuel line for leaks, cracks,
swelling, or other damage. If the breather and fuel
line are damaged in any way, they must be re-
placed. See your Dealer.
WARNING
The ignition system presents a serious
shock hazard. The primary circuit operates
in excess of 250 volts; the secondary circuit
operates in excess of 25,000 volts. Use cau-
tion to avoid injury from shock or injury
resulting from your reaction to shock. Do
not handle primary or secondary ignition
components while the engine is cranking or
running.
Inspect spark plugs periodically. Replace if elec-
trodes are badly worn, insulators are cracked, or if
they are badly fouled.
To remove spark plugs, twist and remove all spark
plug leads. Unscrew spark plug from cylinder head.
WARNING
To install spark plugs, wipe spark plug seats clean
with a clean rag. Install spark plugs finger tight, then
tighten to specified torque. Refer to Engine Speci-
fications.
Leaking fuel is a fire and explosion hazard.
All parts in the fuel system should be
inspected frequently and replaced if signs
of deterioration or leakage are found.
Inspect the fuel system each time you
refuel, each time you remove the engine
cover, and annually.
IMPORTANT: Avoid engine damage by installing
spark plugs into COOL cylinder head and not over-
tightening.
Before installing the spark plug lead, apply a light
coat of Triple-Guard grease to the ribbed portion of
the spark plug. This will help prevent corrosion be-
tween the spring terminal and the spark plug.
