lemur Posted July 31 Report Share Posted July 31 ... and the idle adjuster screw does nothing? Most likely cause; you have a round carb slide inserted 180 degrees from where it should be, a pin goes into a slot in the side of the carb slide and on the other side is a ramp where the idle screw pushes against.
