. What about the the stop screw on the left of the throttle body? Only thing is theres not much adjustment left on it.
That is correct, You DO NOT touch this screw with the spring to lower RPM, that is engine idle speed. You need to adjust the small stud/screw on the side of the Throttle body. Loosen the retaining nut first then adjust with engine running, from cold.
