Weber 2V carburetor
Weber 2V carburetor with vertical flow and automatic choke. The opening of the throttle valves is sequential.
Two-barrel Weber carburetors are installed on OHC and DOHC engines.
The carburetor has main metering systems in the first and second chambers, an idle system of the first chamber, transitional systems of the first and second chambers, a power mode economizer, an accelerator pump, an automatic starting device and an electric intake air heater.
The throttle valve of the second chamber is controlled by the vacuum created in the primary chamber.
Automatic air damper heating is electrical only. The vacuum return valve is integral with the housing.
A distinctive feature of the carburetor is a stepper motor that controls the position of the throttle. This engine is controlled by the MK II electronic ignition control module (ESC II module) and maintains idle stability, as well as controls the throttle position during deceleration, starting and stopping the engine. The result is optimum fuel consumption and low CO levels.
