Default When Timing Dist. which direction advances the timing

I am having a brain fart this afternoon. When timing a Model A which direction do you move the rotor to advance the timing?

The rotor turns counter clockwise when the engining is running so the question is when loosening the cam screw which direction do you turn the rotor to advance the timing.?

Is this a stock distributor that is pined in place by the head, or an aftermarket one that you turn and clamp down? The reason I ask is that you advance and retard the distributor cam to change the timing not the rotor in a original dissy.

This is set up as a standard factory dist.
So to confirm, Counter Clockwise to advance
Clockwise to retard.

Thanks,

Correct, and after setting the timing and tightening the cam screw be sure to apply pressure in the clockwise position to take up the freeplay to make the most accurate final adjustment. Since the advance lever allows 40* advance, which is more than the Model A needs, I don't think being off a couple degrees on initial timing is a big , but I still try to be accurate.
