SPARK PLUG CHECK

Spark plug (2) gap shall be 0.028 ÷ 0.031 in.
A wider gap may cause difficulties in starting the engine
and overload the coil.
A gap that is too narrow may cause difficulties when
accelerating, when idling or poor performance at low
speed.
Clean the scale away from the base of the spark plug
before removing it from the cylinder, after removing the
cap (1).
It is very useful to examine the state of the spark plug
just after it has been removed from the engine since the
scale deposits on the plug and the colour of the insulator
provide useful indications.

Correct heat rating:
The tip of the insulator should be dry and the colour
should be light brown or grey.
High heat rating:
In this case, the insulator tip is dry and covered with dark
deposits.
Low heat rating:
In this case, the spark plug has overheated and insulator
tip is vitrified (glazed), white or grey in colour.
CAUTION*: Carefully change the spark
plug, if necessary, using one having the
same rating.
Before refitting the plug, thoroughly
clean the electrodes and the insula-
tor using a metal brush. Smear some
graphite grease on spark plug thread,
do it fully home finger tight then tight-
en it to 7.37÷8.85 ft-lb. torque. Loosen
the spark plug then tighten it again to
7.37÷8.85 ft-lb.
Spark plugs which have cracked insula-
tors or corroded electrodes should be
replaced.
