In order to properly adjust the distributor advance, the distributor must be removed from the engine and checked
on a distributor testing machine. If you do not have the proper equipment, your local Ford Industrial Products Dealer will be
pleased to perform this operation for you. The distributor advance specifications are given in the Specifications Section.
The spark plugs should be cleaned, tested and gapped at the recommended intervals.
Remove the wires from each spark plug by grasping, twisting and then pulling the moulded cap of the wire only.
Do not pull directly on the wire because the wire connection inside the cap may become separated.

Spark Plug Gapping
After loosening each spark plug one or two turns, clean the area around each spark plug port with compressed air,
then remove the spark plugs.
After cleaning, examine the plug carefully for cracked or broken insulators, badly pitted electrodes, and other signs
of malfunction. Replace as required.
