I think that you are correct, however, the Franco gear advances the cam
(and therefore the distributor) 7 deg at idle/startup, which I think is
outside the window of acceptability for a startup.
Sorry, I/m still unclear from your response why rotating the distributor
to look like it is aligned with the crank at idle/startup won't work. Do
the high voltage terminals become too misaligned for the rest of the rpm
band? Perhaps an inseries electronic time delay could be used, depending
on the nature of the output from the hall-effect sensor.
