It's meant to be screwed all the way in, to provide sufficient tension to the mainspring to insure reliable ignition. Trigger jobs involve other procedures, with minimal attention to the main spring, such as thinning and polishing.
In sum, do not loosen the mainspring screw in an attempt to improve the trigger action.
