Linkert Carburetor Venturi

This Venturi will downsize the 4-bolt M-74 1-1/2" brass Linkert carburetor so that it can be used on a flathead model that originally had a 1-1/4" carburetor.
This Venturi will allow the atmospheric air to pass thru the Linkert carburetor at a faster velocity. This will create 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 accelration off the line. The 4 bolt 1-1/2" Linkert carburetor is a good replacement for the 1-1/4", 3 bolt Linkert on the Flathead and Indian models. Historical note: Developed by Chuck Myles of Sloansville, NY in 2009. Thank you Chuck, as an Indian man.
