Hi Tim
Crank sensor I understand, but you do not need to know which is firing other than standard distributor.

You are correct! Jenvey 4 choke cylinder systems squirt 2 cylinders at a time. I suppose a single carb on a 6 cylinder would squirt all 6 and let the plenum chamber sort it out….. If you had a 3c set up I guess it would squirt 3 times a revolution?
