Alright. This is what happened. The 28 screws that hold the tops on have been in and out at least 15 times in the last few days. I have developed a medical condition called "Weber Back". The symptoms include the inability to stand straight up and severely stretched out hamstrings!
The floats were right, the needle and seats were sealing but we were still flooding. I had been cleaning my fuel filter after each run due to the aluminum shavings in the new tank. That was my fault. I drilled a few holes for AN fittings and, like a fool, I thought my filter would catch the dirt. Well it did but the Russell race filter was a 40 micron filter and it was just catching the big pieces. I had so much crap in the carbs that the needle and seat would get stuck open and not seat properly. That explains the fact the problem would come and go and show up in different carbs. I took all the carbs completely apart and cleaned them, put in a 2 dollar plastic filter right before the carbs and it fixed all but one! So now I start scratching my head. Well the needle and seat, with the crush washer, was setting the float all the way down in the bowl with no "float" and the needle was misaligned with the tang and gas was just running in. I took out the crush washers, set the floats to 4mm above the carb deck and, finally, problem solved.
Important note.
The Weber's were not the problem. They worked as they should. The problem was caused by something else. This is usually the case. I can't begin to tell you how many people told me to switch the intake and go to a four barrel. Well, I'm glad I didn't. To all of those guys, let me quote a famous bumper sticker and say, "Sit down, shut up and hold on!"
