High Idle Please Help

[wildyellow400]

I have a 2004 400ex and i just took the carb apart put in a 155 main and a 42 pilot. Everything went in good except now i have it all back together and it idles really high almost 1/2 throttle, I am wondering whats the matter and also how to fix it. I have my idle screw almost all the way out also. Please help i am new to this stuff.
Thanks Darcy.......

Are you sure the idle screw is turned the right way? check your throttle cable and make sure its not stuck open a little.
