Spark Plug Maintenance:
Disconnect Spark Plug Wire from
1.
end of plug. Clean out debris from
around Spark Plug.
Using a spark plug wrench, remove
2.
the spark plug.
Inspect the Spark Plug:
3.
If the electrode is oily, clean it using a
clean, dry rag.
If the electrode has deposits on it,
polish it using emery paper.
If the white insulator is cracked or
chipped, the Spark Plug needs to be
replaced.
(See Figure cc.)
When installing a new Spark Plug,
4.
adjust the Plug’s gap to the specifi
-
cation on the Technical specification
chart and in the illustration below. Do
not pry against the electrode or the
insulator, the Spark Plug can be dam-
aged.
(See Figure cc.)
Install the new Spark Plug or the
5.
cleaned Spark Plug into the Engine
(61). Gasket-style: Finger-tighten
until the gasket contacts the cylinder
head, then about 1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until
the plug contacts the head, then
about 1/16 turn more.
