I'm still a bit unsure of the vertical linkage rod adjustment from the engine block. This is for the automatic 250SE but I'm posting here as I assume it is universal to the Pagoda too.
Mine is not in a neutral position but I don't want to touch it until I know what to do with it.
Also the arm to the top of the FIP rod has been broken off in the past and I don't know if it was welded on in the correct place...is there any way to check this as it will influence the length of the FIP rod?
Thanks...

Pictures would help. :)

Sorry for the slow reply!
This is the welded arm on the FIP side..
-
And this is the vertical rod I am unsure how to adjust...
It attaches to the linkages of the constant speed solenoid.

I think if you follow the “linkage tour” in the tech manual you will get close if not correct. People that know more about the 250se can comment.
While the throttle linkage crossover bar lever has an ugly weld it does look it was welded at correct angle as far as I can tell from the pic.
Once you set the basic linkage the others fall in place.

Good advice from Mrfatboy.

I think I know what to do :
"The linkage rod going to the block pivot should be set so the venturi is all the way open when the accelerator is at the floor while still allowing the venturi to completely closed when the pedal is up."
I thought I read that this rod also adjusts gear changing timing? Perhaps I misread that.
The car had no problem with warm starting until I "fixed it" (csv was disconnected, linkages way out, wsd not closing) and now it is nearly impossible to start when warm. I renewed the wiring harness so I'm not sure if I put this back in incorrectly. Easy to start from cold.

Rod adjustment will not effect gear changing on a W113 pagoda. Only the later 280SE sedans with the newer "four bolt" pan, automatic transmissions will be affected by adjusting this rod.

thanks!
adjusted now...it was well out so that the venturi was open too early and the pedal couldn't get to the kickdown switch.

My understanding is that there should be about a 1mm gap between the Venturi lever and its stop when the IP fuel lever is on its stop (accel pedal is all the way down). Reason being is you want to be 100% sure the IP fuel lever is totally open when the pedal is floored. The venturi lever adjustment is the place that takes up the tolerance. Having the venturi open 99% versus 100% has little effect on air flow. But there is a difference between the fuel lever being 99% versus 100%. Hopefully that makes sense.
As far as the hot starting, try disconnecting the starting solenoid when starting hot. If it helps dramatically, you are getting too much fuel when it is hot. That is what happened on mine. If there is no change, move on to something else.
