Pull the carb and turn it over, make sure you don't have the throttle blades opened too far exposing too much of the transition slots. This will allow fuel to feed from the t-slot making adjustment with the mixture screws ineffective. The picture blow show a normal exposure, they should show about .020 or look like little squares showing.
