Your idle set screw is too high, and your Air/Fuel screws are out to far.
You need to REzero that carb.
Set the timing with the vacuum hose unplugged...to the highest/steadiest vacuum reading.
Screw both Air/Fuel screws in all the way.
Back them out 1 1/2 turns from seated.
Set the idle to 800ish rpm
Adjust the choke to a light spring back on the choke door....stiffer for longer warm up.
THEN...turn the right side Air/Fuel screw IN till you hear the idle drop....and back out till you hear it increase....the ideal setting is in the middle of that.
Repeat for Left Side....Set Fast Idle to 1100, and idle to 800ish.
Done.
