Neglecting the spark plug eventually leads to
difficult starting and poor performance. If
the spark plug is used for a long period, the
electrode gradual l y burns away and carbon
builds up along the inside part.
In ac
cordance with the Periodic Inspection Chart,
the plug should be removed for inspection,
cleaning and to reset the gap.
•
Carbon deposits on the spa rk plug wi l l
prevent good sparking and cause misfiring.
Clean the deposits off periodically.
•
If the center electrode is fairly worn
down, the plug shou ld be replaced and the
plug gap set to the specified gap using a
th ickness gauge.
