Thanks for your feedback. Here's what I've done so far.
1.Removed the air filter. No change in performance. So I thought fuel must be coming up through the main or slow jet.
2. Squeezed out all of the excess oil from the air filter. Dropped the needle all the way down (clip in top position). It will run and idle ok, and now it will stall as I turn in the pilot screw.
3. It still idles eratically (it is very sensitive to the idle screw adjustment) but does transition well from idle to 1/4 throttle.
4. The bike was a neglected basket case when I bought it. The needle hold-down piece was missing and the air filter was packed with dirt. The needle appears to be slightly bent and "scuffed". The float adjustment was originally set much lower than spec.

Should I replace the main jet along with the needle? I'm thinking I should probably replace the float needle while I'm at it.
