    All end carbs regardless have resin floats.

      6bbl information is so valuable, and made a huge difference in the enjoyment and performance of my 70 V-code Roadrunner.
      Thanks to you and all who contribute solid recommendations!

        I've been doing a lot of testing from information I learned from this thread. My combo ran good beforehand, but I wanted to see if there was more. 62MAX posted a photo on page 1 regarding opening the outboard carbs idle mixture screws 1/8 turn. I read that originally as seat the screws, then open them up 1/8 turn. That did NOT work. So I went back to testing on my own. After doing so, I realized that it probably said to open 1/8 turn further than they were originally opened. Currently, both of my outboard carbs are at 1 1/4 turn from seated. Runs great.

        I'm curious where you guys are hooking up a vacuum gauge? I know it needs to go to a port in the manifold. There is a large port that's currently plugged in the rear of my intake. I'm guessing that is a good place to hook up. Any advise?

          Yup, vac port on the intake rear is fine.

            Or just pull the hose from the PVC and insert it in there.

              The second paragraph of what I posted on page one at the beginning of this thread will correct the problem.Forget about the initial number of turns.Cover the outer air bleed's one at a time and adjust until you have no change in rpm's,once you have all four adjusted go back and reset your initial idle speed.

                THIS!!
                Here's a reminder (I think it's the same thing as 62MAX is recommending) This was an epiphany in tuning my 6bbl!
