Check that the electrodes and the insulator of the spark plug (2) do not show
signs of carbon deposits and corrosion. If necessary, clean them using a
compressed air jet.
Replace the spark (2) if its insulator is cracked, the electrodes show signs of corrosion
or excessive deposits, or the top of the central electrode gets rounded (6).
CAUTION
WHEN REPLACING THE SPARK PLUG (2), CHECK THE PITCH AND LENGTH OF
THE THREAD. IF THE THREADED PART IS TOO SHORT, CARBON DEPOSITS
WILL BUILD UP ON THE THREAD'S SEAT AND MAY THUS CAUSE DAMAGE TO
THE ENGINE WHEN THE CORRECT THREADED PART IS INSTALLED. USE
RECOMMENDED SPARK PLUGS ONLY. USING A SPARK PLUG OTHER THAN
SPECIFIED MIGHT COMPROMISE ENGINE PERFORMANCE AND LIFE. CHECK
THE GAP BETWEEN THE ELECTRODES WITH A FEELER GAUGE TO AVOID
DAMAGING THE PLATINUM COATING.
•
Check the gap between the electrodes with a feeler gauge.
CAUTION
DO NOT ATTEMPT IN ANY WAY TO CHANGE THE DISTANCE BETWEEN THE
ELECTRODES.
04_13
The gap between the electrodes should be between 0.7 - 0.8 mm (0.027 - 0.031 in).
Otherwise, replace the spark plug (2).
•
Make sure the washer is in good conditions.
