Yep, sounds like you've got a blockage in your idle circuit.

I had a similar problem, and discovered that the problem was being caused because I forgot to remove one of the die-cut punch-outs on new float bowl gaskets I installed. This blocked one of the passages for the idle circuit. After removing the punch-out, it worked fine.
