INSPECT SPARK PLUG
NOTE:
-
Do not use a wire brush to clean the spark plug.
-
Do not try to adjust the electrode gap of a used spark plug.
a. Inspect the resistance.
1. Using an ohmmeter, measure the resistance between the insulation and body ground.
Resistance: 10 MOhms or more
If the resistance is not as specified, check the electrode gap.
b. Alternative inspection method.
1. Quickly accelerate the engine speed to 4,000 rpm 5 times.
2. Remove the spark plug.
3. Visually check the spark plug.
4. If the electrode is dry...OK.
5. If the electrode is wet...Proceed to step (c).
