CORRECT OPERATION

Read the condition of your spark plugs to confirm they are operating correctly. It is normal for center and side electrodes to wear away with use due to sparking erosion. The sparks actually consume the metal. In addition, the metal is exposed to the corrosion of combustion gases. Some light colored deposits are also signs of normal operation.
