mo2cyl,
If you go with the Carter-Webers from Langdon and you want to know how to hook up the electric chokes and the throttle rod, just ask here (or search the forums).
Langdon's carb-to-carb linkage is quite nice, but his illustration/photo is hard to understand.
Make sure your fuel system in clean. I put a filter in the fuel line before the fuel pump. I think I might have also put a filter at the inlet of each carb (or, an in-line, clear-body filter between the fuel pump and the carbs).
