I just want to throw this out there, but from my pump tuning experience...
On an M-pump, which is what this thread is based upon, 2f or the full load screw is turned out or ccw to Increase fueling or rack travel.
This is opposed to the rw governor in an MW pump which wants to be turned in or cw for more fuel/rack travel/full load/whathaveyou
