Welcome to the forum. As was said above it sounds like either a air leak or a cable that is not letting the barrel in the carb close all the way. If the intake to cylinder gasket seal is good and the carb is sealed to the intake check the cable. First remove the air filter and twist the throttle and watch the barrel as it moves, do this with the handle bars in different positions to make sure the cable is not binding. As for the mixture you can't adjust it without modifying the main jet size. The best thing to do is get it running correctly as is then after break in do the fine tuning. Ever one of these ive dealt with the miixture was fairly close.
Your results may not be the same,Greg
