Yanking hard at idle???

Sounds like good progress.
You can trim the idle feed and idle air bleeds as needed from there.
The primary IABs are easier to access and a finer trim, so try them first. If they are too big, the engine will have no power on the slightest low speed uphill. These are things you don't forget after experiencing them! Had to go back and learned about sticking wires in the air bleeds before I could go on my way.
