You've got what is a fairly common problem, before you do any more check inside the fuel tank for corrosion same with the fuel filter, lines and float bowls. If you've got any of the above you need to either replace, treat or clean, if you don't the problem will just keep reoccurring, which could well be why after all your work it's playing up again.
Balancing carbs isn't as easy as many would have you believe, it is by definition a balancing act and it's not just the butterfly's. The air jets (pilots) must be set correctly and each carb pulling the correct level of Hg regardless whether they are balanced or not. Then there's the TPS which is a datum, work on only one carb and shouldn't be touched unless it's been played with, again it's set by the level of Hg. The other potential issue is the kit you're using some of the cheap sets of gauges are rubbish, then it's how you use them and adjust.
If you search the board I've made many posts over the years, some are very detailed on how to do the job. Top tips go slow, use good kit and make sure the tank and fuel line/s are clear of corrosion, or you'll be redoing at regular intervals
