Component Inspection

Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug.
Check the electrode. Measure the insulation resistance with an ohmmeter.
If the resistance is less than the specified value, adjust the electrode gap.

Specification: 10 MΩ or more
