I do not believe that the miniscule amount of air coming through the tube when the choke is warmed up will cause a stumble. When the choke piston is at the bottom of its bore it closes off most of the air as I recall, when cold more air comes through to heat the choke spring. As far as the stumble, check engine vacuum at idle, should be 18/19 or so.

Stumble is likely the vacuum advance, check it. Also check operation of accel pump, gas should squirt out of both nozzles.

Let us know what you find.
