I am by no means the Weber guru (hell, I'm working on my first Weber mod and install and there is literally NO INFO on the !@#$ing carb anywhere!!?! (I'm having to gamble on buying a rebuild kit as I don't know if the inlet filter or fuel needle and seat will be the right diameter etc) A pic or 2 goes a long way on gaining insight into throttle cable positions and linkage set ups. My 34DATA requires a single path between the choke arm and the original throttle stop location as any other path will cause the cable to get fouled on something, and I had to alter the throttle stop location as the original adjuster bolt hit the manifold preventing WOT from taking place. It is easy to screw up installing a carb on a non-standard configuration (like having a Weber facing the wrong way will cause the float to shut off the fuel needle and seat sporadically but it'll bolt up and the throttle linkages will work...) so it takes a little creativity, lots of observation, and checking who has done what in the past to get it right.
