Someone, please, the equation for determining the diameter of a bellcrank to be used on a Weber 40 setup. Standard 914 accelerator cable length/throw (full close/full open) and standard Weber 40 butterfly. Also, anyone know of a source for such a bellcrank? Hope not to have to farbricate one myself. No lathe so will have to be with an electric drill for turning power. Extremely primitive.

I sure do!


So in this setup, it appears that both rods link to the carbs at the BACK of the carbs. My carbs are absolutly identical, which means the rod attachments are at the front of one carb, the back of the other. My bell crank is homebrew and designed to accommodate this. I have a hunch that it does not pull equally on both carbs. anyone care to comment on the viability of my set up? Don't hate on the general condition of the rest of the engine bay, I have cleaned it up since i took the pic.

it looks like the parts in the csp link comes with the arms for the carbs so you may not need anything extra (IMG:style_emoticons/default/biggrin.gif)
