CARBON DEPOSIT
Check to see the carbon deposit on the plug.
If the carbon is deposited, remove it with a spark plug cleaner
machine or carefully using a tool with a pointed end.
SPARK PLUG GAP
Measure the plug gap with a thickness gauge if it is correct.
If not, adjust it to the following gap.

ELECTRODE’S 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, 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 damage
may result.
