摘要： A carburetor utilizing high air velocities, and having primary and secondary venturi circuits. The secondary circuit begins to function in response to the primary throttle position, with both circuits fully operating to supply fuel from the ''''pickup point'''' to wide open throttle. The primary circuit is designed to provide maximum manifold depressions of a high order at certain engine speeds.
