So with Tim and Cyber's advice, I finally got the mixture right on the carbs...a little above 3 turns out. It has good throttle response, with no hang (although still a little slow on the decline), nor idle drop below the set idle, as seen in rich mixtures.
So I deem the mixutre good. Next, carb syncing.
#1 & #2 sync together exactly just great. #3 is pretty near where #1 & #2 are.
Here's the problem: #4 (the one with the vacuum line) still has significantly less pull than the rest....and all the seals (tested with WD-40) seem fine...I mean, I wouldn't be getting good throttle response if I had no vacuum, right?
So here's what I think it could be...
1. vaccum leak, maybe not at the airbox-carb or carb-engine seals, but somewhere else?
2. something wrong with Cylinder 4, or the #4 carb?
Here might be an important peice of imformation: When turning the air/fuel mixture screws down to start over, carb #4's screws seats differently than the rest (aka, it's flat head screw is facing another direction when fully seated)
