I have used the Mr. Gasket regulator with dual Carter-Webers but have removed it, with no deleterious effects.
I did not need (or try) to use a regulator with dual original-equipment Rochesters and had no problems after I adjusted poorly-set float-heights inside the carburetors.
Thanks to a PM from Fla54Chevy3100, a few words above now now spelt correctly - the original words led to a very odd meaning. Thanks, Dave
