If you try the 40011 coil, you will need to bypass the ignition resistor under the dash.
As for Dizzy#1 the vacuum brake has little to no affect with today's fuels and personally I run the line for looks but block it off. Set the timing adjust back to the middle and you should be swell.

You need to have 3.9-4.6 Volts at the coil.

Your issue sounds ironically like point float which is why I chimed in, but if both Dizzy's give the same results likely that is not it. HIGHLY doubtful but weak or broken valve spring can cause the same issue. If you pull the choke slightly when acting up does it get better or worse?
