One of the more important issues that you need to be on top of is the linkage for the Webers. Most people spend undue time tinkering with jetting, chokes, etc., when the real issue was that their linkage was not correctly setup and the carbs were operating at slightly different throttle responses. After you have it installed move the throttle lever and watch for any inconsistencies or torquing of the assembly. You may have to add additional support to the bell crank depending on the style. If anything even moves a 1/16" out of sync with the other carbs, it will not run right and changing jetting will not fix it.

Good luck,
