Try adjusting the idle mixture screws with the engine running at the specified idle rpm. Slowly turn in one of the screws until the engine starts to stumble, then back out until it is running smoothly. Repeat for the other idle screw. You may have to go back and forth between the two idle screws and maybe resetting the idle speed screw until you get a good smooth idle. If you can screw the idle mixture screws in all the way and the engine continues to run, then you probably have a float that is set too high or a leaking needle and seat inlet valve. Sometimes a newly rebuilt carburetor will take a little bit of use in order for it to function properly. Good luck.
