I got the plug out, and found the hole over the adjustment screw. Started my machine reved it up all the way, turned the screw and could not tell if it was doing anything. Just wondering if any one else had that problem?

This is the low speed mixture screw according to my mechanic who did this for me and when he set up my new machine. Once my machine broke in I developed a off idle flat spot that I was able to correct by fattening up the mixture with this screw. So yes the adjustments are limmited but appear to be enough at least at this altitude [3000 ft ] to tune for temp changes etc. My machine is running great, tweak with the adjustment it will help some but if your jetting is way off your probably have to do something different .

Is there only one screw on these ones?
