from the threads.
3. Install the spark plug and tighten it to the
specified torque.NOTE:_ If a torque wrench is not available when you are in-
stalling a spark plug, a good estimate of the correct
torque is 1/4 to 1/2 turn past finger tight. Have the
spark plug tightened to the specified torque as
soon as possible. _4. Install the spark plug cap.
