its aparently a way to adjust timing

wouldnt all the lines to the injectors have to goto the opposites?

im not sure if its true yet but i herd it adjust your power curve, that going one way makes it put more fuel at low rpm and another way at high rpm bot sure if thats true or not

the screw in the inlet adjusts the transfer pump regulator. you can make the plungers go out farther by machining the shoe that the roller fits in. I did this to mine 2 years ago and it worked great. went from 13psi to 15 but i didnt take much off of the shoe. what we really need is a 4 plunger head and rotor, parts move less distance to put out the same fuel.
