Well the saga continues. . .
I got it running again last night but it still runs poorly at high power settings. Found water in the tank and filter. Drained both, bought a new diesel can and filled at a high volume pump. Didn't have a new filter so I cleaned the old (3 days old) one best I could. I get what looks to be ample fuel flow through the filter to the lift pump just on gravity. I don't think it's starving for fuel.
It ran OK but not great. I finished the mowing and got the tractor over to the workshop at least so it'll be easier to change the injectors if that's the problem.
Really not sure what's up at this point. Shot a couple of videos.

Sequence of events seems to have played out like this:
-Filled with kerosene which may have been contaminated. . . or maybe
L3200's just don't like straight kero
-Drained tank in field (tractor was sitting at a slight angle) from hose.
-Grabbed another fuel can that may have had contaminated fuel in it (haven't used it in a while either). I didn't drain it first, it had about 1/2 gallon in it. That's probably where the water came from as it was stored outside and is one of the "Ralph Nader spill proof cans without a cap, just a spring seal. I hate those. Took it to down and added diesel.
-Refilled tractor with once again questionable fuel. It ran as expected.
-Rolled tractor downhill to level ground. Drained tank again, found water in tank and filter.
-Refilled from new, known clean container and fuel.
Tractor now runs but poorly and is down on power and has a random miss at high power settings. Could still have some schmutz in one or more of the injectors, or it's possible I've damaged them running kerosene. I'll know once they come in.
Actually after reading the workshop manual that was linked earlier, it does explicitly say No 1 diesel is allowed. Whether or not we agree No 1 is the same as kerosene is still up for debate. . .
