Geez - sounds like you're getting pushed a little out shape. I never cared too deeply why certain functions on the JDB, DB, DB pumps responded as they did - to certain adjustments. What counts is, when you have them on the test stand, they do what they are supposed to do. As I said in the other post, I've seen the low end effect of fuel delivery - from adusting the screw - which determines the plunger-stroke length. Guess I've got the benefit of knowing at the outset that it DOES happen - instead of arguing why it might, or might not. I will admit I haven't spent sleepness nights with my Stanadyne service manual studying hydraulic circuitry. I would if I had a problem to figure out, but I don't. They are pretty simple pumps to work on.
In regard to the post about the Bosch VE, or Diesel Kiki - yeah, they are very different in operation as compared to a Roosamaster DB, DC, or C style pumps. They are also built much better. I never worked on the VE pumps professionally, only on my own - since I've got two diesel 91 Jetta Volkswagens (Bosch pumps), an 85 Isuzu P'UP diesel truck (Diesel Kiki VE clone), and an 81 Chevette diesel (again, Diesel Kiki VE clone).
And one note towards Kieth's way - about diesels not having air-valves. I've got a couple, weird as they are. One is my 1960 International Harverster B-275 diesel with the BD-144 engine. It has an in-line CAV injection pump with an air-controlled governor that attaches to a butterfly valve in the air-intake. Some older Ford diesels have it too - and I suppose others I haven't seen.

New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time. She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had. Jon's Allis has a small front loader and though it doesn't carry much, it serves his needs. It was the hard starting and low power that made him think it was time to replace the old girl. Jon called me to help him discover why his tractor wouldn't start
