Time for a new Carb
I just put a proform 650 double pumper on my 360.Very nice piece and even has screw in air bleeds for tuning if needed.They make the same carb in a vacuum secondary also.Bigger ones as well.Even got mine with the electric choke.Runs like a champ.

Not that you asked but I bet it would really like a dual plane intake.
