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.

QUOTE(Tbrown4x4 @ Sep 13 2019, 02:02 AM)  I bought Mark's bracket and took the cable up through the front engine seal. I also lengthened the rods so they would line up with the carbs better. @Tbrown4x4 Thanks Todd that s info I was seeking (IMG:style_emoticons/default/beerchug.gif) How did you lengthen as the rods are L+R hand threaded, coupling nuts, weld? |
