Seems like a bit of a non-sequitor to me.  You could just as easily conclude
that the emission control system was so effective at ensuring the mixture
burned completely that the engine will continue to burn the mixture (hence
keep running) even with the ignition shut off.  The ARS prevents this by
shutting off the flow of fuel through the carb jets.

But IMO, if you disable the vacuum retard, set static timing to the book
value (around 10-12 BTDC) and adjust the throttles to bring the idle rpm
back down, you won't have any problem with run-on.
