SPARK PLUG GAP
• Measure the plug gap with a thickness gauge. If out of specifi-
cation, adjust it to the following gap.
09900-20803: Thickness gauge
Spark plug gap A
Standard: 0.6 – 0.7 mm (0.024 – 0.028 in)
...................For E-02, 19, 24, 33
0.8 – 0.9 mm (0.031 – 0.035 in)
...............................For E-03, 28
ELECTRODES CONDITION
• Check to see the worn or burnt condition of the electrodes.
• If it is extremely worn or burnt, replace the plug. And also
replace the plug if it has a broken insulator, damaged thread.

Confirm the thread size and reach when replacing the
plug. If the reach is too short, carbon will be deposited
on the screw portion of the plug hole and engine dam-
age may result.
Do not cross thread or over tighten the spark plug, or
such an operation will damage the aluminum threads
of the cylinder head.
