More bad news, the shop I had wanted to take the 300D to is in the
process of closing and selling all tooling and servicing material. It's
called Superior Diesel Service in Richmond, Va if anyone is interested
in tools, etc.
Now I have to widen my search for potential service centers....
If anyone knows of any shops convenient to central Va please let me know...

Thanks Peter,
I replaced seals, o-rings and springs when I redid the work
Wednesday.... I agree - replace all three, although in the past I
have re-used the springs.

you MUST replace the copper seals, they work harden and will never
seal twice.
They are cheap, but shipping will usually bite you (as in $10 for
shipping and $2 for seals).
The o-rings just seal the fill chamber from leaking out, maybe 30
psi. The copper seals keep full pressure in the injection lines, if
they leak you have no injection at idle (or poor injection very
late). Makes the engine shake like crazy.
Also check for a leaking injection line, although they usually make a
huge mess with diesel fuel leaking all over if they are bad.
A stuck injector will knock badly and give you excess vibration too.
