First off, what, exactly, has changed from when you ran the 12.3 to the 13 flat? Is the carb new or did it run the 12.3 on this carb?

You really should not need a squirter that big. I'd recommend that you go back to the squirter that came with the carb, which is probably a 28 or 31, and go to a stiffer secondary spring. I'm guessing that the secondary spring is too soft and is basically flopping open, causing a bad bog. Holley secondary springs are cheap and easy to change.
