Can anyone help me out here. Quad when returning to idle the RPM's dip low and sometimes enough to stall out the quad?

I have tweaked with the air/fuel mix and it idles perferct and throttle response is decent but it dips and sometimes stalls. Thinking maybe going 1 step leaner on the needle?

Fought the same problem for a day or two. I started over with the carb tuning. I went about 1.5 turns out from seated on air fuel to start. Made sure I could idle ok. Once idled ok tweaked air fuel to get idle to go up some but still have the throttle response. Eventually I got there but it took awhile.
