What is wrong with your idle that you need to fix? The base idle speed set (BISS) screw is only used to center the idle speed controller within its range. Odds are if you're having an idle problem, it's something more than the screw being out of adjustment. Nevertheless, here's the vfaq page for adjusting the BISS screw. http://www.vfaq.com/mods/BISS-1G.html
The www.vfaq.com site is very helpful if you've never heard of it before. You'll find that many of your questions can be answered there without the hassle of starting a thread.

Best of luck!
