Do some reading on how carburetors work, understanding the venturi effect among other concepts will help. The carburetor you will likely find on an older American car are going to be different than the SUs or Strombergs (also found on British cars) but the operating principles are similar.

Look up "constant depression" or "constant velocity" carburetors to figure out the operating principle of the Stromberg or SU carbs. It'll make it easier to tune them if you know what they are doing.
