With the 84, don't you need 12V to run a fuel pump, and regulator? (4's run at like 1 to 1.25 LBS fuel pressure.
The way I take what Bob suggested is time the engine at TDC with the lever down 4 notches. So 4 notches down on the quadrant is 0° advance.

Not sure what a "84" is but 6v fuel pumps are available.
