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.
