Of course it comes all the way out, it is made that way. When adjusting you only need to pull it out far enough to clear the notched ring. Make your adjustments one notch at a time if you aren't using a set of gauges and keep track of your starting point. If you screw the pooch and get it too far out you can always return to the starting point.
