Loosen the idle screw about four turns from tight (not too tight) turn the dajuster IN on the top of the carb as far as it will go, or until you hava a little freeplay ther. See what happens. If those two don't do it, look inside the carb via the air cleaner opening to see if the slide is going all the way down. If it's not one of the above there is an air leak somewhere.
