Are you able to achieve a sensible idle by lifting the linkage by hand in order to close the throttle (i.e. pushing the throttle lever on the carb onto the idle stop)? I had the same issue on mine and resolved it temporarily by moving the return spring nearer to the arm (the coiled spring had crept away from the arm's pivot point and so weakened the return pressure, leaving the mechanism a bit floppy).
