You obviously know your stuff! That is exactly why I could not go ADI, which I would have preferred to do.
The setup is a mid-70s up in-line fours and sixes clamp on cap distributor. Other than a problem with carb clearance (it's tight!) the system was easy to convert to and eliminates those clunky car coils, ballast resistors, points, etc. It ran super from day one, and NOW is running great again--took her for a spin yesterday and it ran perfectly.
So why the high rough idle that goes away when it feels like (and hasn't returned--for now)? Dammed if I know! Been messing with engine for 60 years and this one has me stumped.

PS: FOrgot to add: I converted a Mark 55 type tower and FGS to the power head so I don't "wreck any docks".
