3) Ground the spark plug's (-) electrode (threaded section), pull
starter to check if there is spark at the electrode joint.
Warning
Never touch spark plug's terminals by wet hand when testing.
If touching the high tension cord by wet hand, starting can
produce a high electric voltage, which is very dangerous.
Sprinkled fuel can cause fire around the spark plug. First,
clean the fuel, then check.
