Maintenance and Tune-Up:
Spark Plug Gap
Measure spark plug gap with a thickness gauge. Adjust
to within specified range if gap is out of specification.
Special tool
: 09900–20803 (Thickness gauge)
Spark plug gap "a" (Standard)
0.8 – 0.9 mm (0.031 – 0.035 in.)
Condition of Electrodes
Inspect electrode for a worn or burnt condition.
If it is extremely worn or burnt, replace spark plug.
Also, be sure to replace spark plug if it has a broken
insulator, damaged thread, etc.
CAUTION
Confirm the thread size and reach when
replacing the plug. If the reach is too short,
carbon will be deposited on the threaded
portion of the plug hole resulting in possible
engine damage.
