Turn it to the opposite direction that the rotor rotates.
Rtr. turning clockwise. Rotate distributor counter clockwise to advance timing, clockwise to retard.
Counter clockwise to advance.......clockwise to retard
counter clockwise.
Loosen the bolt holding the distributor in place, and turn the distributor counter clockwise. If it bucks the starter, it is too far advanced.
cam timing will not change ignition timing i would try 8 or 10 degees advance at idle with the vacuum advance disconnected.
Loosen the distributor, and turn it counter clockwise. This should be done with a light in measurable amounts.
Distributor Advance is the wrong term; the Distributor Advance system implies actually moving the timing components of the distributor to control timing of spark in the engine (A Vacuum Advance, is an example of this). Modern controls use computer spark mapping, through learned routines or factory set timing models to control the spark based on these tables, through the computer. In all essence it is the computer that controls all spark functions.
The vacuum canister can advance 24 degrees beyond initial timing.
you turn the distributor and use a timing light
No need to if the distributor was not moved.
Clockwise.
