The Autolite 2100 is a two venturi (barrel) carburetor manufactured in multiple variants by Autolite from 1957 to 1973. Eight sizes ranging from 190 cfm to 424 cfm were made, all with synchronized venturis, variously with manual, electric, or automatic hot-air chokes.
Autolite 4300A Carburetor. The Autolite 4300 was a four-barrel (four venturi) carburetor manufactured by Autolite in multiple variants from 1967 through 1974. Used by both Ford and AMC, it was produced as an emissions-compliant replacement for the previous Autolite 4100 model, and was superseded by the Motorcraft 4350.
Of the three types of carburetors used on large, high-performance aircraft engines manufactured in the United States during World War II, the Bendix-Stromberg pressure carburetor was the one most commonly found. The other two carburetor types were manufactured by Chandler Groves (later Holley Carburetor Company) and Chandler Evans Control ...
Problems of fuel boiling and vapor lock can occur in carbureted engines, especially in hotter climates. Since the float chamber is located close to the engine, heat from the engine (including for several hours after the engine is shut off) can cause the fuel to heat up to the point of vaporization.
The Motorcraft 2150 is a Ford (also used by AMC) 2-barrel carburetor manufactured from 1973 through 1983, [1] based heavily on its predecessor, the Autolite 2100 carburetor. The 2150 improved on the 2100s design through the introduction of a variable air bleed system, which keeps the air to fuel mixture better balanced throughout the carburetor ...
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
Carburetor icing is caused by the temperature drop in the carburetor, as an effect of fuel vaporization, and the temperature drop associated with the pressure drop in the venturi. [2] If the temperature drops below freezing, water vapor will freeze onto the throttle valve, and other internal surfaces of the carburetor. The venturi effect can ...
The much smaller primaries act as a small two-barrel carburetor until the accelerator is pressed far enough to start to open the secondaries. The small primaries allow the primary throttle plates to be opened wider, and thus making the carburetor more efficient than a large two barrel, or square bore four-barrel. Drivability.
