Thanks for the conversation last night. I'm staring at the pump now, and I am now not sure how I am to locate the port you described.
I attach a pic of the pump.
I prepared the pump area and took lines off, and pulled glow plugs to ease turning it. I also removed the intake manifold so I could access and see the pump. When I crank it, I get good squirts from #2,3,4, but # 1 just drools. I notice slight contact marks on the delivery valve holder where it contacted the clamp, and i can see where it was originally in contact...about 20 degrees different.
Before I get digging into the works, I will have you look at the picture to establish the pump model, and talk further. I also may rotate the valve holder of #1 back to where it looks like it came from, and see if I get a squirt from #1 vs a drool. If I get a squirt, I'll reassemble...it needs a head retorque anyway now that it has run on the new head and gasket...check the valve lash, etc then run it.

It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
