Thanks for the replies. Ok, so i am going to make up some steel fittings to use rubber hoses for ease of making changes. And i guess it sounds like i should start where i have it set now. Ill pull all 8 plugs after runs and check to see how distribution looks with this staggered setup. I just was under the impression that only the rear was staggared , but when i think about it, the front and the back has shorter and longer runners feeding opposite sides of the carb. So i guess that’s the reasoning for differing the front and rear plates.
I have the outboards idle screws at 1/2 turn, and i’m showing just square on the transfer slot for center carb, which brought me to just about 1/2 turn on idle speed screw. The outboards also have 1/8” holes on the throttle plates already.
