Carter Double Pumper?

I'm working on it now. But not in that fashion. I'm trying to use the stock passages. I had to put the project down for a bit but I'm about ready to restart the problem solving machine again. I need to get free time (OMG-LMAO!!!! ) to mess around with it.

I seen a picture of one and enquires to the owner about it who refused to spill the beans. He simply said "Good luck on figuring it out."

I don't think I can do it on a TQ so easy. But that's next.
But first things first, the AFB! I'm using a 600 FWIW.
