Rebuilt Pinzgauer engine, hard starting, smoke....

[Sethsquatch]

Hey all!

So my Pinzgauer has been in the shop for over 4 months now (!) and is finally back together, and running. It basically has new everything, from the head gasket up, turbo, injectors, injection pump, etc.
Now that it's back together, it has a hell of a time starting, like several cycles of the glow plugs, cranking for 30+ seconds before it finally catches and idles, this being on a cold day. (40f)
As soon as it started, it ran good, but smoked a lot, black smoke at idle and more as it was driven and revved.
I have heard there's adjustments on the timing of the pump, and also on the pump itself as far as lessening the fuel...I'm not a technical person, which is why I had a shop do the work, and he's fairly confident he has the pump timed correctly. Just wondering if there's a diagram of that pump somewhere of the adjustments on it. Also any advice you'd have to dial it in.
Thank you so much!
