clean the carbon deposits from the spark plug with a
small wire brush or spark plug cleaning tool.
Inspect the spark plug electrodes (A) and (B) for
any corrosion. If found any replace the spark plug
with new. Visually inspect the spark plug gap. The
gap should be
0.9 ~ 1.0 mm
for
UR5KCW

1.0 ~ 1.1 mm
for
ZRG8MC4
. If the gap is found to
be more than the limit replace the spark plug with a
new one.
