Constant Velocity Carburetors:
The constant velocity carburetor, often referred to as a CV carb, operates through the use of a slide, tapered needle, diaphragm, and a butterfly. The throttle cable is not connected to the slide, it operates the butterfly which is located on the engine side of the carburetor. As the butterfly is opened more air is able to flow in. This changes the air pressure in the bore, pushing up the diaphragm and drawing the slide and tapered needle with it. Similar to the cable slide carburetor, when the needle is raised more fuel is supplied and as the butterfly opens more air is added to the mix.
