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(jeffdon @ Dec 29 2010, 11:15 AM)  I have a hunch that it does not pull equally on both carbs. anyone care to comment on the viability of my set up? Unequal pulling/pushing is unacceptable. You should be able to adjust your carbs so that they hit WOT at the same time and flow the same volume of air at idle. I'm a fan of home built stuff, but you gotta be 100% accurate with this type of thing or you're engine may not run smoothly or you may be tossing money away in wasted fuel. A carb linkage should have ZERO slop or wobble. It should move both carbs equally, and it should be simple. QUOTE(mrbubblehead @ Dec 29 2010, 11:32 AM) do you think this is a better setup than the hex linkage from cb performance? 100% better. I will NEVER recommend hex linkages again. They are all horrible. QUOTE(ConeDodger @ Dec 29 2010, 12:34 PM) Is this what I should be using for my Jenvey's Mr. McMark? I think so. (IMG:style_emoticons/default/sunglasses.gif) QUOTE(anderssj @ Dec 29 2010, 12:43 PM) 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? It looks like they'll work. |
