Swapped to Electronic Dizzy, Ran for a minute, now it won’t start!

I think you have a fuel AND an ign issue.
Ign.
[1] Check all 8 reluctor tip gaps. I have had reluctors that were out of round. If the tip makes contact on that cyl, there will be no spark. If you find a variation in the gap, find the tighest gap & set that to 0.008". Also make sure that the rel & shaft are tight, no looseness.
[2] Reluctor phasing. Most rel have two slots in them, because the SB engines rotate in the opposite direction to the BBs. This allows one reluctor to be used in both engines. The wrong slot could have been used which causes all sorts of misfire etc. Compare to another SB dist if you have one. If not, the rel turns CW. The ign fires just as the trailing edge of the rel tip passes the p/up node. At that instant, the rotor tip should be pointing at a segment in the cap. If not, the wrong rel slot has probably been used.
