If it starts to sound a lot smoother and you need to ease on the gas really carefully to rev it up, it's too lean. It also might "gallop" slightly (best way i can describe it).
If the engine sounds like it's stalling from simply running too slow to stay going, and the sound of the individual power strokes is really distinct, you're probably running rich or you're idle is too slow. If I were you I'd turn in the idle speed screw a full turn or something (so it idles really fast) until you get it running right.
You tuned it when it was fully warmed up, right? Because that's what matters, the whole purpose of the choke is to temporarily change the a/f ratio for when the engine's cold.
If you need to leave the choke on all the time tho, then obviously you're too lean.
I have a feeling you're idle speed is set too slow, and you're naturally trying to make it idle faster by making it run excessively lean. Which causes it to bog out and die every once and a while because it's right on the edge of being too lean to run (very fine line, it'll be like falling off a cliff).
