It's a good question. Sometimes one can find that a particularly heavy oil in the dashpot, which makes the piston slow to rise, means that the restricted choke increases the airspeed over the jet and briefly richens the mixture, the opposite of what one might expect.
If perchance your piston is undamped and could rise very quickly with the cornering forces (which I doubt) you might stall the airflow briefly and so weaken the mixture. Just playing devil's advocate. Since this is something of an academic discussion, why not?
More to the point, I do wonder if you are experiencing a fuel surge effect. If the fuel climbs up the float chamber wall and permits the float to drop you might get an overfull float bowl briefly as the needle valve is fooled, especially if the fuel pressure is high. The exact problem Miss Shilling's restrictor mitigated, under much more arduous conditions of course.
What pump are you using? An SU or mechanical pump should be ok. An unrestricted Facet could be a problem.
