It was succeeded by the Motorcraft 2150 carburetor. Flow rate is determined by the diameter of the venturi, which was cast into the float chamber side as a number within a circle representing the venturi size in inches: 0.98 - 190 cfm, 1.01 - 240 cfm, 1.02 - 245 cfm, 1.08 - 287 cfm, 1.14 - 300 cfm, 1.21 - 351 cfm, 1.23 - 356 cfm, 1.33 - 424 cfm [2]
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 ...
As the airflow through the carburetor increases the reduced manifold vacuum pulls the power valve open, allowing more fuel into the main metering circuit. In a two-stroke engine , the carburetor power valve operates in the opposite manner: in most circumstances the valve allows extra fuel into the engine, then at a certain engine RPM it closes ...
Lars Grimsrud is an aerospace engineer and performance automobile enthusiast who has become a celebrity amongst owners of carbureted Chevrolet Corvettes and GM muscle cars for his skill at tuning their engines.

The Ford variable venturi carburetor was replaced by a Weber 28/30 TLDM which used a manifold vacuum-actuated secondary choke instead of the more usual sequential linkage which opens the secondary butterfly at 3/4 to full throttle. The 1.4 L version is less responsive to power modification than other CVH engines, and some common tuning parts ...
Manifold vacuum, or engine vacuum in a petrol engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the airflow through a throttle in the intervening carburetor or throttle body leading to the intake manifold. It is a ...
