Good evening all, I need some relief from my car. Just finished 2 weeks ago a full engine swap with a very good engine from another 79' 300D. I should mention though that my Red 79' had a bad motor which was a 1980 block with low compression. It now has a 1979 block in it with very good compression. The injection pump is the one from the 1980 block and does NOT have the green sticker.
I am STILL having a problem with VERY slow acceleration from 0-10mph when car is cold. After car warms up completely and I stop at a traffic light, it wants to die and gradually has more problems idling in drive while stopped until it gets to the point where it will only move about 10 feet even while I'm flooring it before it dies. It seems like it is not getting enough or any fuel.
What is done already:
-totally clean fuel system with 3 brand new filters and auxiliary boost pump with a clean tank strainer, no moving bubbles in clear filter
- clean air filter with no blockage
- new glow plugs and relay
- new priming pump with no signs of leakage
- new injector nozzles bench tested good
- checked length of idle pressure relief spring, good at 26 mm
- new torque converter and transmission with no shifting, or flaring issues
- has been running on pump diesel or B20 lately but was run on WVO for a few months on the old engine

Engine idles strong in neutral or park and has decent power at highway speeds. It is slow to rev up however even in neutral and then sometimes acts like its going to runaway presumably because I have the idle set somewhat high with the cable to prevent it from dying on the way home.

I went to go find my rack damper bolt to adjust it but to no avail.
Where is it on this car? Not on the back of the IP like on my 1985 300D.

What else could be the culprit? It seems I have narrowed my issue down to fuel injection by eliminating the much more difficult components (ie, new engine, torque converter, checked transmission). Does anyone have prolific advice for me? I promise I'll send you a twelve pack if you can get me moving here.
Thanks and God bless.
