Hesitation at 60 mph and up

Im not sure how the pump is, as far as I know its ok.
I believe the screw is turned back a bit.
I had stall out issues after it was put on the road and the mechanic had to readjust it now and then to bring the idle back up. He then disconnected a small hose on the carb and the stalling issue went away.

This feels a bit different.
