.

as I remember from some old whunter's posts linkage must be
free for movement,and stop lever has to move freely also...
mine would not budge,pls see vid:

linkage.mp4 - YouTube

smells like (yet another) trouble?

Check the linkage going to the IP from the shut off lever.

Your Bowden cable seems to be okay, just missing the protective cover.

Does it drive okay?

linkage to IP when moved by hand does go down (not easily anyways...)
when pushed by stop lever it would not budge at all

car drives more or less fine,but sometimes I have problem with gas pedal response.. it does have some kind of lag .... weird...

it confuses me as I watch some other guy video where he can easily
move down stop lever button.....

Not your vehicle but in the W123 Manual the Linkages have specific lengths listed. Measuered from the Center of the Linkage Balls or Linkage Holes.

Another issue is that inside of the Idle Adjustment Screw is a Spring and Plunger that allows the Throttle Lever to go into the Shutoff Positon; I read x2 where that Plunger or spring were Rusted up inside and either would not move or had limitied movement.

You have a big problem with the linkages.

Four questions:

1. Has the motor ever been replaced on this car?

2. Is your idle speed very slow right now?

3. When you press down on the accelerator, do you feel like the linkage is "pushing back" at first, before it moves?

4. If you look on the inside of the injection pump (the side nearest the motor itself), do you see the idle adjustment screw and locknut assembly? I cannot see clearly enough in the video to make out if it is still there.

Right now your stop lever appears to be resting against the valve cover.

thank you for video mate!

in basics,we have same setup,and mine acts like yours
in video you press stop lever toward engine,and mine moves also
in that direction, but refuses if I try push it towards me (opposite way)

in some dudes video he easily did that and when I tried (for fun) I
notice that it would not obey

2. nope,it is even bit bigger than it should be

3. yes,you might say that

4. adjustment screw and locknut assembly are still there

You're welcome, my lever does not pull back (push it towards me) either, no need to, I would think.

Sorry I didn't read your signature line before I asked if it had an engine change... .

I asked that because when I had the motor changed out in my SD, when I got the car back from the garage it had the same problem. I had to go look at another car at a recyclers' yard, take photos, then put the linkage back together correctly. Unfortunately that was in 2005 and I no longer remember exactly how I fixed it.

I would start by looking carefully at toomany MBZ's video and comparing the linkage setup to yours. I think you may have one or more linkages installed in the wrong place (wrong length). Or a small piece is missing somewhere.

I asked about the adjustment screw because if the bracket that holds it in place breaks off (which happened to me), then the whole linkage starts to behave as you describe. But that is obviously not the case with your car.

ok, finally done,every rod was 5mm or so out of specs. and I readjusted them but one thing blow my mind off (or..out )...

I have found connecting rod that goes to actuating lever on the pump VCV disconnected, even more when I pulled it out I found that it was previously broken and welded (badly)... go figure! ...so I made new one from 6mm steel bar with exact 122mm distance.

now it seats fine,...btw, what was I missing during this dis-conecction?
(I have driven car without this connection for month or so...)

AFAIK, the VCV lever is a vacuum bleed for the transmission, the faster you travel, the less vacuum the transmission needs.

Not sure why I plugged off the bleed orifice.
