Periodic maintenance and adjustment

is too long, overheating and engine damage
may result. If the reach is too short, spark plug
fouling and poor performance may result. Al-
so, if the reach is too short, carbon will form on
the exposed threads resulting in combustion
chamber hot spots and thread damage. Al-
ways use a spark plug with the specified
reach.

Before installing any spark plug, measure the
electrode gap with a wire thickness gauge
and adjust to specification.

When installing the spark plug, always clean
the gasket surface. Wipe off any grime from
the threads and tighten the spark plug to the
specified torque.

NOTICE

ECS00382

Make sure that the spark plug caps are se-
curely installed. Otherwise the spark plug
caps could be damaged due to engine vi-
bration.
