Your idle mixture screws should have a larger range of adjustment than you've described, but that's neither here nor there at this point.
Adjust the 2'ndary blades tighter, then idle mixture screws, then idle speed- if needed. See where that leaves you.
After you get the idle where it's stable, work on the accelerator pump adjustments if the stumble is right off idle.
