NationMaster - Encyclopedia: Weber carburetor

Weber carburetors were originally produced in Italy by Edoardo Weber as part of a conversion kit for 1920s Fiats. Weber pioneered the use of twin barrel carburetors with two barrels (or venturi) 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.

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.

Mercedes-Benz Ponton Type 220S Weber Carburetor Conversion (1873 words)
	Weber kits are well known and frequently used on virtually all carbureted cars and trucks in the world.
	The heart of the Weber conversion kit is the adapter plate system that mates the Weber to your existing OEM intake manifold.
	The primary weakness of all Weber manufactured adapters is that the plates are die cast instead of milled.

Technical Department - Downdraft Carburetor Tuning Guide (5281 words)
	Most Weber emulsion tubes are fat in some sections, skinny in others, to carefully fine-tune the rate at which the mixture changes (or the precision with which it is maintained) with the airflow rate into the engine.
	One of the main differences between the Weber and the Hitachi is that the secondary throttle plate is opened by manifold vacuum on the Hitachis and by a mechanical linkage on the Weber.
	The Webers secondary throttle begins to open when the primary is 2/3 open, on the Hitachi the secondary opens when two conditions are met- the primary is open more than two-thirds and the manifold vacuum increases beyond a certain point.
