What is the method for adjusting spark plug gap?
1 Answers
Spark plug gap adjustment method is: 1. Pull the feeler gauge by hand to sense and remember the tightness during pulling; 2. Select a feeler gauge with the same thickness as the desired gap; 3. Hold the spark plug with one hand and tap the electrode tip with a wooden stick using the other hand; 4. After bringing the lower part of the electrode into contact with the feeler gauge, pull the gauge; 5. Adjust until the tightness matches the initial pulling sensation. The function of a spark plug is to introduce high voltage electricity from the ignition coil into the engine cylinder, generating a spark between the electrodes to ignite the air-fuel mixture. The components of a spark plug include: terminal nut, insulator, terminal stud, center electrode, side electrode, and shell.
