Today I call the Edelbrock Carburetor tech line just trying to get some baseline ideas on carburetor Theory when operating two carburetors at the same time. Oh boy, so what I got was a guy telling me which carburetors I should buy but I'm telling him I've already got carburetors and which ones they were and he assured me that I couldn't run those. I assured him I've been running them very successfully for 4 years and was looking for some operation Theory when running two together. He didn have a clue....
