I believe the issue is a torn or holed accelerator diaphragm. I am going to pull the carb off again and see if I can put my hands on a rebuild kit. I hope the accelerator pump diaphragm is part of the kit.
Er...y'mean you opened and closed the carburetor without a rebuild kit? Yikes! That's a terrific way to set the car on fire. That bowl gasket is a one-use-only item. Yes, you need a rebuild kit, and you should put in a new float, too. Walker kit number 15480A, Walker float 100-14.
