Check Spark Plug Gap
Use a spark plug feeler gauge to check the gap between
the two electrodes. When the gap is correct, the gauge
will drag slightly as you pull it through the gap.
If necessary, use the spark plug gauge to adjust the gap
by gently bending the curved electrode without touching
the center electrode or the porcelain.
Seat Adjustment
The seat can also be adjusted forward and back. Move
the lever (A, Figure 11), position the seat as desired, and
release the lever to lock the seat into position.
