I spent about 30 min with my tool on the two problem injectors and didn't get the NBRs out, but I did get one injector out. It came out pretty easy with a jar from the puller.
I never checked warmth, but I did notice BAD pulses from 2 and 3 (Where is one? Front IIRC) When you crack the bleeders they sputter fuel out and 1 and 4 you can see a rythmic pulse. I never heard a change in engine performance when cracking injector bleeders.
Hopefully timing isn't a problem, but I doubt it has been timed in a long time. Wet stacking doesn't seem extreme, but is certainly present. ie waiting in line to tractor pull or waiting for a full chopper box when the haylage stinks.
Yeah, front is one. It certainly should not be oiling the pipe like that. A common timing procedure is to advance until exhaust clears up (in the high rpms), then back off slightly.
It almost seems like it has troubles in the distributor valves, but that will usually affect all. I would pull injector #2 and #3 apart and inspect for dirt/damage. Easy to do. Pay attention to the disc filter and what may be in it, and the valve. A dribbler (common problem) can cause a lot of bad effects.
Another point of timing. Load affects it, as the plunger is driven by a cam. The more load, the more lead (and lag) you end up with, with the inherent effects that accompany. Mostly this mean low loads don't burn as well.
