It is PAT, but no problem.
How carefully did you check the section about examining the throttle cables?
Pull on the throttle cable outer housing at the top of the carburetor. At
throttle off idle position, there MUST BE a minimum of 1/16" of freeplay in
the outer cable. This verifies that your slide has actually reached the idle
stop at the bottom. I really suspect your cable is too tight and the carb
slide is hanging off the end of the cable instead of resting on the tip of
the larger, exposed, knurled idle speed screw. If the cable is loose, then
maybe something inside the carb body is holding the slide up. Also possible
that you have the slide installed backwards in the carb body?
Remember, the smaller, recessed screw controls the air/fuel ratio at idle
speed. Won't make much difference at all if the carb slide is being held
open and the bike is running above idle speed.
