SPARK PLUG
Spark plug inspection
0.8–0.9mm
Measure the spark plug gap with a thickness gauge. The
standard spark plug gap is 0.8–0.9mm. If the measured
spark plug gap is out of standard range, adjust or replace
it with a new one.
Whenever removing carbon deposits, be sure to observe
the operational color of the spark plug’s porcelain tip. This
color tells you whether or not the standard spark plug is
suitable for your type usage. A normal operating spark
plug should be very light brown in color. If the spark plug is
very white or glazed in appearance, it has been operating
much too hot. This spark plug should be replaced with a
colder plug.
