Weber Carburetors

Weber pioneered the use of two-stage twin-barrel carburetors, with two venturis of different sizes (the smaller one for low-speed/rpm running and the larger one optimised for high-speed/rpm use).

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

In 1986, Fiat also took control of Weber competitor Solex, and merged the two into a single company (Raggruppamento Controllo Motore, or the "Engine Management Group").

[3] Genuine Weber carburetors were produced in Bologna, Italy, up until 1992, when production was transferred to Madrid, Spain, where they continue to be made today.

Weber fuel system components are distributed by Magneti Marelli, Webcon UK Ltd., and, in North America, by several organizations, including Worldpac, marketing under the Redline name.

[citation needed] Weber carburetors are sold for both street and off-road use, with the twin-choke sidedraft DCOE (Doppio Corpo Orizzontale E; "Double-Body Horizontal E") being the most common one.

[8] These numbers are followed by a group of letters, which indicate various features: the DCOE is a sidedraft unit, all others being downdraft; the DCD has a piston-type starter valve as opposed to a strangler choke; and so on.

[11] Copies of DCOE, IDF, IDA or DGV carburetors can be found made by other companies, like EMPI, FAJS or REEDMORAL, LOREADA, often at up to half the price of the authentic Spanish Weber versions[citation needed].
