Yes that is right, but with a different regulator it is a lot less worse. Tested on 3 1HDFT engines, most std pump maxed out. Same results so I dont think the pump is bad. Took some pictures for you about the timing piston. I guess there is some room left, so the spacer might work IF the case...

Seems that a differend shimmed pressure control valve will control the internal pump pressure a lot better than the original one. Messing around with the timing piston wont help when there isnt sufficient pump pressure on the high output pumps. Measured the pressure a few times and it will drop...

Yanmar is 12mm

Ft camplate is already 3.2mm

Your compressor wheel is way too big.

The spring is very stiff. Almost not compressable by hand. Also very hard to replace when the pump is on the engine.

Wont fit either.

I would try with smoke and/or vacuum in the intake.

Main fuel screw not tightened?

Probably a bad engine install method?
