Pressurize Carburetor R1
To get your vacuum carburetors to work with Turbo you need to pressurize them
You need to pressurize above and below the diaphragms
You also need to pressurize the flout bowls
This instruction is for the R1, but the principle is the same on all vacuum carburetors
My carburetor setup is stock except Needle down one clip (leaner)
Above the diaphragms
On the R1 you have two holes in the slide that will pressurize the top of the diaphragms.
