The Loadomatic distributor timing advance was vacuum only, there were no flyweights. The vacuum supplied to the distributor was through a special passage in the carburetor and was varied by throttle opening. Effectively they were a matched pair. The advance specs varied between brands (Ford, Mercury, Lincoln) and likely by engine displacement. Any other type of carburetor will not supply the proper vacuum signal to the distributor. The engine will run with the wrong type of carb, but not very well except within a vary narrow range of RPMs and load. Performance and gas mileage will be the pits. It wasn't one of Ford's better ideas.
