Measured from surface of casting flat where gasket sits to what? Asking because I just rebuilt the Tilliston on my A. Now its idling rough, but best with the idle screw all the way in. Stalls when I back it out more that a 1/2 turn. Idle smooths out considerably with the manifold vacuum line open.
Runs fine at higher rpms

My thinking is it is running too rich due to hight float level Thats why it smooths out with the vacuum line open. I just kinda guessed on the float level.

So, my question, float level measured from surface of casting flat where gasket sits to what? No horizontal seem on my float.

thanks
