SPARK PLUG CHECK
Spark plug electrodes gap shall be 0.7 - 0.8 mm (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 off any dirt around spark plug base before removing
the spark plug.
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.
