Yes, a 4 barrel carburetor can be used on a 2 barrel intake, with an adaptor plate for this purpose but it will not perform well with the adapter. A 2 barrel is a twin venturi or twin choke carburetor. Both barrels open at the same time. They are small and are usually used on the smaller engines. A 4 barrel carburetor has one half the same as the 2 barrel called as the "Primary" side. The other half is called the "Secondary" side and it does not start to open until the primary side has opened part way. It may be opened mechanically or by means of a vacuum signal from the intake.
