plug must be properly gapped and free of
deposits.

If the engine has been running the muffler will
be very hot. Be careful not to touch the muffler.
2) Visually inspect the spark plug. Discard it if
the insulator is cracked or chipped.
3) Measure the plug gap with a feeler gauge.
The gap should be 0.7-0.8mm (0.028-0.031
in),Correct as necessary by bending the side
electrode.
4) Attach the plug washer, thread the plug
by hand to prevent cross-threading.
5) When mounting a new spark plug, you
should screw 1/2 more thread with the wrench
after the washer is compressed. If you are
mounting an old one, you should only screw
1/8-1/4 more thread.

tightened. An improperly tightened plug
can become very hot and possibly damage
the engine. Never use a spark plug with an
improper heat range.
