Using the spark plug spanner, remove the spark

A spark plug with heavy carbon deposits will not
produce strong sparks. Hence, only if necessary,
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 a new. Inspect the spark plug gap with a wire
gauge / feeler gauge. Readjust the spark plug gap to
1.0 ~ 1.1 mm if required.
