No it does stall out.
I have since made some more progress. With some more playing around, it now is nearly perfect. The air screw is turned out about 3 turns, idle is right down low. I can barley see past the slide like you mentioned.
The throttle is snapping shut.
So for the most part, the miss is gone. I sometimes get a bit of a quiver or a stumble in that same throttle range, I am going to adjust the float height once more and I have a feeling it will cure it. I think its a bit high.
Im almost there haha
