Been fiddling with the idle mix adjustment screws a lot. Doesn’t seem to make much difference.
That’s usually a sure sign you still have an obstructed pilot or air jet.
Edit:
So you apparently don’t have a pilot jet, it’s called an “idle pickup tube” in the diagram below. Make good and sure it and the 2 air bleed passages are clean (there is one pickup tube and 2 air passages per “barrel”).
Keep in mind that only shows the idle circuit. But that’s probably where your problem is. Also double check float height if you haven’t.
