when you take the cover off the Gov, you see what holds the spring. hold the pin part so that the spring does not turn out and turn the part that looks like it was made for a wrench. turn it 1/2 turn to tighten the spring, then try it to see if that worked, if not go 1/2 turn more and try it, if that didn't do it, go 1/5 turn in the other direction and try it.
