The
Weber DGV series, 2-barrell, progressive down-draft carburetor, as used on both
the Ford 1600cc Kent (Formula Ford) and 2000cc (Sports 2000 & Ford 2000),
remains one of the most simplistic, yet tunable components on these and many
other, small bore race vehicles.
Normal servicing may be required to keep the internals clean of foreign materials, both airborne and those delivered from the fuel system. Occasionally inspecting the float settings are required, because of the miles traveled to and from events. Many of these units have been modified by engine builders, with small tubes running into the airstreams, thus care must be observed when performing any service or jet change function.
Adjustments normally carried out by an individual, would commonly be a Jet change. The Jets, just below the top cover (remove six screws), are know as Air Correctors (also, high speed bleeds). When those jets are removed the emulsion tubes are exposed (function = mix air and fuel). These have been known to get plugged with grass, tire rubber and grit, that somehow, can by-pass an air filter assembly. In the bottom of the float bowl, is the Main Fuel Jet. Both of these Jets, are measured in mm, in .05mm increments (1.45mm, 1.55mm, etc.) and sold as such.
Some common service parts are as follows.
