So I eventually decided ti go with a weber. Ordered a 32/36 from webercarbsdirect. It looks like if I could just mount the mikuni arm to the weber, this would be a breeze. Problem is that there isn't enough room to bolt it on next to the one the weber comes with. The instructions say something about a spacer you can grind down, but don't see what they are referring to. There is also the issue of the weber arm having a hole for the arm that comes down from the choke. Even if you bolt the mikuni arm on next to the weber one it will interfere with the kickdown mounting point.

What did you guys do?
