WEBER Carburettor Tuning & Jettings
"We do all of our tuning in house on Land & Sea system Chassi Dyno Rolling Road"
**For the normally aspirated racing or high performance car, the Weber
carburettor is probably the ultimate choice. It was designed to be adapted
for use on any engine size, for any purpose, at any altitude. The Weber is
not a carburettor to be bought, bolted on and driven, it is infinitely
adjustable and is intended for the serious performance tuner. In modern
times, fuel injection, the electronic technology revolution and stricter
laws regarding pollution emissions have led to the carburettors demise
(the last one was produced at the Bologna plant in 1992). Weber
carburettors are still used extensively in Classic and Historic racing**

From Wikipedia, the free encyclopedia
Eduardo Weber (November 29, 1889 - May 17, 1945) was an Italian engineer and businessman, famous for creating the Weber carburetor.
He was born in Torino to a swiss father and mother from Piemonte. After graduating in mechanical engineering from the Università degli Studi di Torino (1913) he moved to Bologna to work for Fiat. He was a tutor to Amédée Gordini and, at Mugello, he raced a Fiat 501 to third place in June 13, 1920.
His work to remedy high gasoline prices resulted in the first Weber carburetor, a "sidedraft, double-throat ... bolted to a Weber designed overhead-valve/supercharger conversion for the 501 Fiat". In 1923 he established the Fabbrica Italiana Carburatori Weber company.
Weber was with the Italian Fascist Party. After his disappearance in May 1945, Fiat eventually assumed control of the company in 1952.
He is buried in the Certosa di Bologna.
Weber is an Italian company producing carburetors, currently owned by Magneti Marelli Powertrain S.p.A., in turn part of the Fiat Group.
The company was established as Fabbrica Italiana Carburatori Weber in 1923 when Edoardo Weber (1889–1945) 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.
After Webers death in 1945, Fiat finally assumed control of the company in 1952. 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, Renault, 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.
Weber Carburetors are sold for both street and off-road use, with the twin choke sidedraught DCOE being the most common one. They are sold in what is referred to as a Weber Conversion kit. A Weber conversion kit is a complete package of Weber Carburetor, intak
