[Vwdiesel] Rebuilt IP / Engine Won't Start

I've got a rebuilt IP pump that I just put on my rebuilt engine.  I'm having 
trouble starting it.

I used new turbo piston in my 1600NA engine, and I ridge-reamed and honed 
before installing them.  Ring gaps are to specs.

My compression from 1-4 is: 380, 385, 380, 375psi.

I believe this compression is low, but know that the rings haven't seated 
yet, and those are figures for a stone cold engine.

When I crank over the engine for a long time it ALMOST wants to run, and a 
couple of times I have been able to get it to run for a few seconds.  I 
found that by backing the idle screw all the way OUT, it seems to want to 
run a little bit more.

However, if I step on the throttle it dies immediately.  Is the governor set 
wrong?  How do I set the governor?

Other ideas?
