To remove a spark plug:
(1) Remove the hood. (See page 22 for hood
removal and installation procedures.)
(2) Remove the spark plug cap.
(3) Remove the spark plug, and then check
the condition of the spark plug and the
spark plug gap. If the electrode portion is
significantly discolored, if electrode ero-
sion becomes excessive, if carbon and
other deposits are excessive, or if the
spark plug gap is not within the specified
range, replace the spark plug.
TIP:
When the engine is operating normally, the
color of the spark plug electrode portion will
be a medium-to-light tan.
To install a spark plug:
(1) Wipe off any dirt from the threads, insula-
tor, and gasket surface of the spark plug.
(2) Install the spark plug, and then tighten it
to the specified torque.
TIP:
If a torque wrench is not available when you
are installing a spark plug, a good estimate of
the correct torque is 1/4 turn to 1/2 turn past
finger tight using the spark plug wrench in-
cluded in the tool kit. Have the spark plug ad-
justed to the correct torque with a torque
wrench as soon as possible.
(3) Wipe off any water or dirt inside the spark
plug cap.
(4) Install the spark plug cap by pushing it
down until it is securely installed in its
original position.
(5) Install the hood in its original position.

(2) If the choke knob moves back on its own,
tighten the choke knob adjusting nut
slightly. If the knob is difficult to move,
loosen the adjusting nut slightly.
