3. Inspect the spark plug. Replace it
if the electrodes are worn, or if
the insulator is cracked or
chipped.
4. Measure the spark plug electrode
gap with a wire-type feeler gauge.
Correct the gap, if necessary, by
carefully bending the side
electrode.
The gap should be:
0.6 – 0.7 mm
5. Install the spark plug carefully, by
hand, to avoid cross-threading.
6. After the spark plug seats, tighten
with the spark plug wrench to
compress the washer.
