So here is our 3rd tutorial in the series on the operation of Weber DCOE carburetors, this time focusing on the main circuit.
Through the needle valve (1), the fuel (Yellow) reaches the tank where the float regulates the opening of the needle valve (2) so that the fuel level remains constant.
This fuel is mixed at the emulsion tubes (4) with the air (blue) which arrives at the top of the air correction jets (3) to produce the air/gasoline mixture (green) which is then in turn discharged into the carburetion zone through the conduits (5) and auxiliary venturis (6).
