Sounds like a vacuum leak. You're overcoming the vac. leak with more fuel but if it's bad enough it won't stay lit. Might check your plugs and see if they are wet from flooding.

I had the same problem and it ended up being that I was using a universal carb. gasket on the autolite (now edelbrock) and it was a tiny bit too narrow allowing air to get sucked in. I could keep it running by goosing the throttle every second but if I let off of it, it would stumble and die. Have a friend start it up while you spray carb cleaner around the base of the carb, and around the intake manifold. If it evens out while you're spraying you have a vac leak. Also check any vac lines you have (brake booster, auto tranny modulator, vac. guage).
