2-6 PERIODIC MAINTENANCE
SPARK PLUG GAP
• Measure the spark plug gap " with a wire gauge.
• If it is not within the specification, replace the spark plug.
* To prevent the damage of iridium center electrode,
use a wire gauge to check the gap.
* Never adjust the spark plug gap.
Spark plug gap:
Standard: 0.8 – 0.9 mm (0.031 – 0.035 in)
ELECTRODE'S CONDITION
• Check the condition of the electrode.
• If it is extremely worn or burnt, replace the spark plug.
Replace the spark plug if it has a broken insulator, damaged
thread, etc.
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.
