I have had issues with PHBH carbs where the screw-in tick-over adjuster doesn't actually do anything. Either the "point" is too short, or the external spring is too long.
It is not wrong to adjust the cable to get a tick-over. The screw AND the tightened throttle cable are doing exactly the same thing, by lifting the slide to allow more air beneath.
