In theory, I cound apply .5 volts to the D terminal when the starter is engaged and retarding the timing by 10 degreed thus making it faster start ?

Waid

The 5 volts volts to the "D" terminal WILL retard the timing by 10 degrees.
That part isn't theory.
If you need to retard your engine that much to start it, makes me wonder what your initial timing is.

Sorry, I was typing .5 volts and it is actually 5 volts.
