Weber carburetor

Weber is an a Italian company producing carburetors, currently owned by Magneti Marelli Powertrain S.p.A., in turn part of the Fiat Group.

The company originated in the 1920s when Edoardo Weber produced carburetors as part of a conversion kit for Fiats. Weber pioneered the use of two stage twin barrel carburetors, with two venturis of different sizes, the smaller one for low speed running and the larger one optimised for high speed use.

In the 1930s Weber began producing twin barrel carburetors for motor racing where two barrels of the same size were used. These were arranged so that each cylinder of the engine has its own carburetor barrel. These carburetors found use in Maserati and Alfa Romeo racing cars. Twin "updraught" Webers fed superchargers on the 1938 Alfa Romeo 8C competition vehicles.

In time, Weber carburetors were fitted to standard production cars and factory racing applications on automotive marques such as Abarth, Alfa Romeo, Aston Martin, BMW, Ferrari, Fiat, Ford, Lamborghini, Lancia, Lotus, Maserati, Porsche, Triumph and Volkswagen.

Genuine Weber carburetors were produced in Bologna, Italy up until around 1990 when production was transferred to Madrid, Spain, where they continue to be produced today.

In the United States Weber Carburetors are sold for both street and off road use. They are sold in what is referred to as a Weber Conversion kit. A Weber conversion kit is a complete package of Weber Carburetor, intake manifold or manifold adapter, throttle linkage, air filter and all of the necessary hardware needed to install the Weber on a vehicle.

In modern times, fuel injection has replaced carburetors in both production cars and most modern motor racing, although Weber carburetors are still used extensively in classic and historic racing. They are also supplied as high quality replacements for problematic OEM carburetors. Weber fuel system components are distributed by Magneti Marelli, [http://www.webcon.co.uk/ Webcon UK Ltd] , and, in North America, by several organizations, including Interco Products Corporation, Worldpac, marketing under the Redline name. Other suppliers include Overseas Distributing and Pierce Manifolds.
