SPARK PLUG (FIG. 2, 13)
Use recommended spark plugs, see
Product Specifications for correct
spark plug. To ensure proper engine
operation, the spark plug must be
properly gapped and free of deposits.
If the engine has been
running, the muffler will be very hot. To
reduce the risk of injury, allow cooling
before proceeding.
1. Remove the spark plug cap.
2. Clean any dirt from around the
spark plug base.
3. Use a spark plug wrench (not
supplied) to remove the spark
plug.
4. Visually inspect the spark plug.
Replace it if the insulator is cracked
or chipped. Clean the spark plug
with a wire brush if it is going to be
reused.
Risk of unsafe
operation.
Always wear certified safety
equipment: ANSI Z87.1 eye protection
(CAN/CSA Z94.3) with side shields.

plug washer is in good condition.
Thread the spark plug in by hand
to prevent cross threading.
7. After the spark plug is seated,
tighten with a spark plug wrench to
compress the washer. If installing
a new spark plug, tighten the
spark plug 1/2 turn after it seats to
compress the washer. If reinstalling
a used spark plug, tighten 1/8–1/4
turn after the spark plug seats
to compress the washer. Do not
overtighten.
8. Securely replace spark plug cap.
NOTE: The spark plug must be
securely tightened. An improperly

which have an improper heat
range. Use only the recommended
spark plugs or equivalent.
