EDIC stopped working? after oil change

ok, gotta EDIC question that fits nicely in here.

so as long as I have been aware of and touched the edic/fuelscrew/fuelpump zone in the car, this particular part has been this way. so the edic motor has na arm that connects to a little rocker thing that gets pushed forward or backward. forward shuts it off, backward turns it on.

that rocker thing though has a "window of movability", i attached a pic of what i mean. that little arm can swing between 2 stops the two yellow lines i drew. so right now on my car when the car is on, the arm pulls back towards the fire wall, and that little rocker on the fuel pump is pulled back wards, but the part that is supposed to stop when it hits the fule screw, does not hit it. I can push it so it touches the fuel screw, and it has some spring resistance and returns to where it was when i turned it on. basically my fuel screw isn't performing any function right now. it seems like the edic is not pulling back far enough. like needs to still travel a 1/4" to hit the screw.


nooooooow all that said, when i started this thread i had never had my hands on the fuel screw before. so when i touched it for the first time, i found that it was fully loose, and backed real far out. at this time, i was making more black smoke under load and up hills then i did before. after backing the screw back into what looked like a reasonable spot. the motor performed way better and went back to an expected amount of soot after that.

Is it possible that I still have the screw backed out way too much? or is the arm not pulling back to where its supposed to?

like in this picture, is the fuel screw screwed in a normal amount? cause mine is still backed out much more then in this pic.

any insight appreciated :)

l'm revisiting mechanical experiences of 30yrs ago with the ute, so l'm rediscovering the how too's again..much like yourself. Have a word with Dougal or Duncan..they're diesel savvy on the 2H in the 47's.. How bad is the soot ?...does it decrease the further in you turn the fuel screw ?...or does the engine search for fuel (starved)... l assume (don't take my word for it)... you can screw it in until the engine dies due to fuel starvation, then gradually unscrew it until it idles happily...(counting the turns)...that way you can acquire an 'ear' for how it sounds when its near or at 'spot on'.
