Soba - after re-reading all this couple of times I'm not convinced that you do understand waht is trying to be explained. It's so darn hard to see those pictures in another guys head isn't it? HA.
To make it a skoche easier please look at my Picturetrail account shown here and on the pick up photos you'll see one named Carbureutor Linkage. It shows the two carbs (not the ones you have) the rod between them and the center lever that the vertical rod attaches to. This is somewhat different than the Offy linkage (which I'm still looking for)and available from Stovebolt Engine Company. I do have the Fentons on this motor and don't know why it takes Rigatoni to make it work. I made my own vertical linkage from 1/4" stock and cut the threads on it.
