To understand the principle, a study of illustration 17 should be made.
The automatic timing control is a taper fit on the shaft for the inlet cam, retained by a
central bolt. The cam separating the contact points is rotated by two pegs engaged
in the plates for the unit springs.
As the cam is detachable, the position of the cam should be noted, before it is removed.
Before setting the ignition timing it is essential to check the contact breaker gap.
CHECK C O N T A C T BREAKER GAP
(See also Electrical Service.)
Remove two screws securing the cover mounted on the timing case, also the cover.
Rotate engine to fully separate contact points.
Check the gap which should be ·014—·016".
To adjust the gap release slightly the two inner screws securing the fixed contact plate
and adjust the gap as required by moving the pivot plate in the required direction.
REMOVING T H E A U T O M A T I C T I M I N G C O N T R O L
After taking off the cover:
Remove the two screws passing through the slotted holes in the fixed contact breaker
plate and remove the plate.
