New Carb problems

about 2 weeks ago i readjusted my carb it was running really really rich. well i finally got it re adjusted and now the idle hangs around 1000-1200 RPMS it really annoys the hell out of me. i have 3 carb springs on it to bring it back plus the factory spring on the accelerator cable so anyone have any ideas? the idle screw is all the way out so i know it isnt the problem
