Or maybe something like this from the Accel DFI Instructions:

• Using a carbureted style distributor: If you are using a distributor from a carbureted engine that has centrifugal advance, you must lock down the advance and install an adjustable phase-able rotor (if possible) to prevent engine kickback while starting.
(Failure to do so will cause numerous issues that include: Broken starters, no start conditions, spark scatter and erratic timing).
