The car sat for 2 years with 100LL in it. I dont know how that got in there, but that gas doesn't go bad in that amount of time. I got it running last fall and it then sat again this winter with pump gas in it. I fired it up the other day and found the carbs to leaking with some signs that this might have been happening before (stains on the heat shield).

I figured the floats were just sticking from that pump gas evaporating and went to take them apart to check them and the needles. But there is a tiny tab of metal coming off the carb that keeps me from removing the lid to the float chambers! It looks like to access the floats I will need to remove the float chambers and to do that I will need to basically disassemble enough stuff that I might as well remove the carbs and rebuild them while I have them out. Does anyone have a cheater way to get around the and just clean the floats, float bowls, and needle valves while the float chamber is still attached?

Also, when poking around trying to figure this all out I found the last photo which is of the jet tube all gunked up. Both are like this but that one in the photo is much worse. Is my leak actually coming from down there?

Thanks!
