Hey, im installing a 2TG into one of my toys, now i know the carbs had a spacer plate between the carb and manifold. Was this purely a spacer or did it do other things.. It looks like it also joined 1+2 and 3+4 runners together so that the PCV etc can be plumbed into the 2 holes on the actual carb manifold (the 2 between 1+2 and 3+4 runners)
Am i on the right track here? did it serve any other purpose? previous owner removed to fix clearance issues..
I've seen them used. but never used them myself. I always thought there purpose was to do just what you said, and balance both throats of the carbs. And also to aid vaccuum to your brake booster. I run 40mm webers and no spacer and just run the vaccuum line to my booster off #4 intake runner.
