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.

The absolute best bellcrank I've seen is this one from CSP.
It's extremely rugged. Really, really well built. And even uses ball bearings for the rotation. Such a great product and worth every penny. |

QUOTE(McMark @ Dec 28 2010, 11:17 PM)  The absolute best bellcrank I've seen is this one from CSP. It's extremely rugged. Really, really well built. And even uses ball bearings for the rotation. Such a great product and worth every penny. Looks VERY nice! CSP's web-site says the linkage fits Weber IDFs, but no word on Dellorto DRLAs. I'm thinking that if CB Performance hex linkage fits both, then the CSP should too. Anyone using this on Dell's? Thanks! Steve A- |
