With this flange you can easily mount the Polini CP, DellOrto or other brand carburetor that you have always dreamed of to your machine.
The flange is mounted on the plug and then the carburetor is mounted and tightened. What this does is for example can keep the original studs.
Note: The flange only applies to carburettors that are NOT with "male" connection to the socket. We recommend looking at the dimensions of the flange, in the last picture.
