Do you see the petcock near the bellhousing? That is where the other end of the spring on the bell crank goes, around the petcock. You spring is not the right spring so you will want to get something that looks like the one in Mother Truckers photo. Next, weld a little tab on your bell crank linkage, the linkage that goes straight up to the carbs, drill a a small hole in the tab and install another spring. Run this spring down to the pan and hook it to the pan ledge. The tab is better but in the absence of a lower tab, the pan method will work.
the other thing is that the linkage that connects the two carbs does not have enough slop in it to allow the carbs to fully close. You may have to make up some new linkage that allows for a tiny bit of slop on the part of each carb to get them both to seat completely on just the spring pressure.
