Some thoughts:

When cold and the choke is operated, that would be closed, not open.

Usually best to close choke fully, run starter only a couple of revs (2 seconds) and then crack the choke open a bit, maybe closed only 3/4, and try again a little longer. At the first sign of a fire, blip the throttle just a tiny bit.

Once started don't open the choke all the way until it warms up. You should be able to find a point on the choke where the engine will idle a bit fast without racing. While the little beast is somewhat erratic while cold, mine never dies if I leave the choke on just a bit for the first 2-5 minutes.

This could also be a sign that the idle speed (when hot) is set too low.
It could also be a sign that it's time for some carb cleaner in the gas......or that the air filter is getting dirty.

And no, Alan, there is no thermostat; it's just the crappy lean lo-speed carb mixture setting that causes it.
