SPECIAL 29.4mm (1-11/64") VENTURI for 1-1/2" 4 Bolt Linkerts This Custom Machined Alloy Venturi will allow the atmospheric air to pass thru the Linkert carburetor at a faster velocity. This creates a better vacuum to allow the gas to be pulled up from the bowl, thru the main nozzle with the result of better starting, and greater acceleration off the line. The 4 bolt M-74B 1-1/2" Linkert carburetor is often used as a replacement for the 1-1/4" 3 bolt Linkert on hopped up Flathead motors. This Special Venturi will downsize from the stock M74B 1-5/16" Venturi so that the Carb can be used more successfully on a Flathead motor that originally used a 1-1/4" Linkert.
