Spark Plug
A. Spark Plug Gap
B. Outer Electrode
The spark plug should be taken out periodically for
inspection and regapping. Measure the gap with a
wire-type thickness gauge. If incorrect, adjust the
gap to the specified value by bending the outer elec-
trode.

If the plug is oily or has carbon built up on it, clean
it. The plug may also be cleaned using a high flash
-point solvent and a nonmetal brush (nylon etc.). If
the spark plug electrodes are corroded, or damaged,
or if the insulator is cracked, replace the plug. The
standard spark plug is shown in the table below.

To find out whether the plug’s heat range is correct,
remove the plug and examine the ceramic insulator
around the center electrode. If the ceramic is light
brown, the spark plug correctly matches the engine
temperature.
If the ceramic is black, the plug should be replaced
with a hotter plug.
