I see no one has responded.
Your choke high-idle cam may be picking up when the regular idle speed screw is backed off all the way.
If that's not the case, you might take the carb off and turn it over. Check the opening of the secondaries, they might be held open too much.
Other than that, I wouldn't worry about it if it runs okay otherwise.
