I added a small piece of metal to the lever of the carburetors ( W-1s ) so I open the carburetors by pulling down. See the circle in the attached photo. Everything is polished or black so pictures don't come out to well. The green intake in the second picture is the same one, you can see how the linkage works. Cable pulls back towards the cab pulling the links down via stock GM bell cranks. The green intake has Rochester Mono-jets installed, I swapped them for W-1s and painted it black.
