idle speed control motor

I am trying to set my isc to spec. It says in my manual to fully retract the idle speed control motor then if the isc screw is touching the throttle turn it in untill there is clearance and the throttle is resting in the minimal idle screw. Problem is the isc screw still touches the throttle when screwed in all the way and fully retracted, should i cut the screw down so it will screw in further? someone help thanks.

No, it is either the wrong one or you do not have it backed up all the way.
