●
Wipe off any water on the spark plug or
inside the cap before installing the spark
plug cap. Push the spark plug cap down
until it is securely installed.
●
If a torque wrench is not available when
you are installing a new spark plug, a good
estimate of the correct torque is 1/4 turn to
1/2 turn past finger tight with the spark
plug wrench included in the tool kit. Have
the spark plug adjusted to the correct
torque with a torque wrench as soon as
possible.
