The
Weber DGV series, 2-barrel, 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, normally due to the riggers of traveling by trailer to an event. 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 upper 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 below them are exposed (function = mix air and fuel). These have been known to get plugged with grass, tire rubber and grit, that somehow by-pass fuel and air filter assembly. In the bottom of the float bowl, is the Main Fuel jet. Both of these Jets, are measured in .05 mm increments (1.45mm, 1.55mm, etc.) and sold as such.
Some common service parts are as follows.
