The only service or adjustment to the ignition coil is the air gap between the coil and the flywheel. The
only time air gap needs to be set is if it has been removed or tampered with. There are adjustment
slots on the coil to allow for up and down movement on the coil. The primary and secondary coil can
be tested by inspection (see below).
