After cleaning, dress the electrodes with a small file to obtain flat parallel surfaces on both the center and side
electrodes. Set the spark plug gap to specifications by bending the ground electrode. All spark plugs new or used should
have the gap checked as required.
Install the spark plugs and torque each plug to specifications.
Connect the spark plug wires.
NOTE - Do not over tighten spark plugs. The gap may change considerably due to distortion of the plug outer shell.
