Examination
8. Examine the removed candle. If the spark plug electrodes are covered with oil or wet, then there is a misfire or it is caused by poor condition of the piston rings. Have the compression checked by a workshop.
9. Check the gap between the electrodes using a template.
Attention! For new spark plugs, the gap between the electrodes is usually correct.
10. Bend the side electrode to correct the gap. Perform bending by tapping on the side electrode. To bend the side electrode, use a small screwdriver, resting it on the edge of the thread, but in no case on the center electrode, otherwise it may be damaged.
