Spark Plug Replacement and Adjustment
The spark plug type NGK B 8ES or ND
W 24 ES is standard for these models.
1. Detach the spark plug lead and remove
the spark plug with the special wrench
provided in the tool kit.
2. Inspect the electrodes and center porce-
lain of the spark plug for deposits,
eroded electrodes, or carbon fouling.
If the spark plug deposits are heavy, or
the electrodes appear to be eroded
excessively, replace the spark plug
with a new one. If the spark plug is
carbon or wet fouled, the plug can
sometimes be cleaned with a stiff wire
brush.
3. Adjust the spark plug gap (D to
0.028-0.032 in. (0.7-0.8 mm).The gap
can be measured with a feeler gauge.
The adjustment is made by bending
the negative (grounded) electrode @.
