This exclusive Berg 48IDA auxiliary venturi is aerodynamically designed to provide higher air flow than the stock Weber part it replaces. The larger 5.0mm passage delivers the additional fuel capacity and more volume to the engine with less signal from the engine, with normal size jets. Often required by high horsepower engines. Commonly required with carbs that have been modified to 51, 51.5 or 52mm. Requires that the carb is drilled and tapped to locate and hold it in place with a set screw (use GB 501-SS which is included with the stack). Shorter and more streamlined for better flow into the carb throat. Sold per each. Made in the USA by Gene Berg from 1992. |
