Re: running rich??

You could just leave them alone, it sounds like they are closed all
the way! As for running rich to cure you might need a complete tune-up
and clean the fuel injectors. Start by making sure you don't have any
vacuum leaks and the control pressure regulater is getting electric
and the vacuum hoses to it are hooked up right. Also make sure there
is a plug in the opening over the mixture screw or you have a large
vacuum leak. You don't use the brass screws except for setting the
mixture screw which if you don't touch should be OK. If it bothers you
they can be drilled out and replaced.
