•
Clean the spark plug, preferably in a sandblasting device,
and then clean off any abrasive particles. The plug may
also be cleaned using a high-flash point solvent and a wire
brush or other tool.
If the spark plug center electrode [A] and/or side elec-
trode [B] are corroded or damaged, or if the insulator [C]
is cracked, replace the plug. Use the standard spark plug
or its equivalent.
•
Measure the gaps [D] with a wire-type thickness gauge.
If the gap is incorrect, carefully bend the side electrode
with a tool to obtain the correct gap.
Spark Plug Gap: 0.7 ∼ 0.8 mm (0.028 ∼ 0.031 in.)
•
Insert the spark plug vertically into the plug hole with the
spark plug installed in the plug wrench [A].
