4.3. CLEANING THE SPARK PLUG
- Remove the spark plug with a suitable tool and adapted to the type of thread. Check the level
of carbon build-up and discoloration.
- Remove the carbonization remains. Adjust the distance between the electrodes (0.7 - 0.8
mm).

In the case of fitting a used spark plug, tighten it only 1/8 to 1/4 turn after inserting it by hand to
compress the washer.
