why were downdrsft su carbs developed
A carburetor is a device which mixes air and fuel for an internal-combustion engine. Carburetors are still found in small engines and in older or specialized automobiles such as those designed for stock car racing.However, most cars built since the early 1980s use computerized electronic fuel injection instead of carburetion.oday, most automotive carburetors are either downdraft (flow of air is downwards) or side-draft (flow of air is sideways). In the United States, downdraft carburetors were almost ubiquitous, partly because a downdraft unit is ideal for V engines.
