If you have the idle speed screw on the throttle linkage turned up enough to uncover too much of the transfer slot you will be pulling fuel from the main circuit not the idle circuit...That is usually what causes one not to respond to the mixture screws. Get the timing ironed out and you may be able to back off on the speed screw and get back on the idle circuit. Drilling the holes Charlie mentioned will help this too..more air gets through so you maybe can back the screw out some.
