3. Fouled (black, wet or dry, dark deposits, grey, melted coating)
The plug face reveals the condition of the engine,
operating condition, method of driving and fuel
mixture. For this reason it is advisable to inspect
the spark plug at prescribed intervals, examining
the plug face (i.e. the part of the plug projecting
into the combustion chamber).
Spark Plug Installation
Spark plug installation is the reverse of the re-
moval procedure. However, pay attention to the
following.
Prior to installation make sure that contact sur-
faces of the cylinder head and spark plug are free
of grime.
Using a wire type feeler gauge, set the electrode
gap to 0.7 – 0.8 mm (.028 – .032 in).
Apply a light coat of heat sink paste (P/N 420 897
186) over the spark plug threads and gasket.
Hand screw spark plug into cylinder head until it
bottoms out.
Torque spark plug to 20 N•m (15 lbf•ft) using an
approved spark plug socket and torque wrench.
Apply Super lube (P/N 293 550 030) to the elec-
trical contact inside the spark plug cap before in-
stalling it on the spark plug.
