From what you are explaining, either no or slow gas flow to the carbs, or you did not clean them well.
did you remove every single jet, even the one under the blind plug? The pilot circuit is responsible for idol, and will run the way you have explained if clogged. If you have a steam cleaner, use it to put pressure on all the circuits and clean them out. I have never really had good luck with the carb dip because the clogged circuits keep cleaner from entering and doing their job.
