When fitting the plug, always clean the

gasket surface and use a new gasket.

Wipe off any dirt from the threads and

screw in the spark plug to the correct

torque.

NOTE:

If a torque-wrench is not available when

you are fitting a spark plug, a good esti-

mate of the correct torque is 1/4 to 1/2 a

turn past finger-tight. Have the spark plug

adjusted to the correct torque as soon as

possible with a torque-wrench.
