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 vaccum 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.
