Early 2L non turbo diesel in a 1986 4runner. It's very sluggish, struggles for 60 km/h goin up hills. I've noticed anything above 2/3 throttle the truck doesn't accelerate at all, the engine tone doesn't even change, but black smoke will go out the tailpipe.
I'm wondering if the injectors are maybe due for replacing, or maybe I can adjust the fuel screw. EGTs are fine. Even when I free rev it, it'll spew a little smoke.
Here's a few videos if they help at all.

As far as I know, the fuel screw is in the stock location, but again, I don't even know how to tell.
