Scottie,
To add to X-file's comments, if the idle will not come down it is probably because either the slide is not closing fully or there is an air leak bypassing the slide. Check the mounting to the head/inlet manifold carefully. Too loose/poor gasket can cause an air leak, overtightening can cause the slide to stick. Also check you have sufficient free play in the throttle cable. Of course excessive wear in the throttle slide will also cause air leaks.
Once you get the idle to come down set the idle mixture as follows. With engine at normal operating temperature adjust the idle screw to give a fast idle. Screw in the mixture screw until the engine starts to bog down then screw out the mixture screw until the engine starts to bog down. Half way between these two points should be the correct setting, which as X-file said, should be about 1-1/2 half turns out. You should then be able to set the idle to your desired setting.
