spark plug mounting to avoid their entry inside
the cylinder.

produce strong sparks. Hence, only if necessary,
remove 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 one.

After cleaning and inspecting the gap, reinstall
the spark plug and tighten by hand to avoid cross
threading. Finally tighten using the spanner. Do not
over tight or cross thread the spark plug.
