Inspect the spark plug. Replace it if
the electrodes are worn, or if the
insulator is cracked or chipped.
Clean the spark plug with a wire
brush if you are going to reuse it.
Measure the spark plug electrode
gap with a suitable gauge. The gap
should be 0.024 0.028 in (0.60
0.70 mm). Correct the gap, if
necessary, by carefully bending the
side electrode.
Install the spark plug carefully, by
hand, to avoid cross-threading.
An incorrect spark plug can cause engine damage.
