Hi John, glad to hear you are happy with it. The idle screw is not needed if you get the washers under the cam exactly right, but I only seem to get it every 4th or 5th time, just pot luck. The main reason I started removing the built in kill switch was because you get people who want to force the lever back too hard and then the switch would jamb because of the design and then they would try and push it back and the cable couldn't get it to free from the switch. It is a pain fitting another kill switch but at least it comes up against a solid stop so it can't jamb up
