Checking the spark plug

The spark plug is an important engine component,
which is easy to check. Since heat and deposits
will cause any spark plug to slowly erode, the
spark plug should be removed and checked in ac-

cation chart. In addition, the condition of the spark
plug can reveal the condition of the engine.
