Starting spark frequency? (ignition issues...)

Checked this morning and only have 300 mVAC from the plug on the distributor side of the connection. Is this enough to trigger the control module?

However I did notice the car acted like it wanted to start after the key was released and a little smoke came up through the carburetor. Not sure what this means.

I'm going to get something to label my plug wires at the distributor and then take a look under there. After I charge the battery I'll also check for starting voltage of the brown wire from the starter relay. I wonder if something is going on there since, based on what was said above, the ballast should have nothing to do with starting at all.
