Fuel Air Mixture.....Bluebird won't stay running.

[Chadahar]

1984 Euro 500SEC,

I have searched on this forum for a definitive answer and there have been none come up.

It starts and runs for a second or so, then quits. I'm positive it is in the mixture screw. I was turning it bit by bit CCW and it died. Feels like it isn't getting fuel or is flooded, but it does start.
I checked the fuel line in and out of the FD and the pump is working great, filled the bottom third of a 1 liter soda bottle very shortly, a second or so. So the pump works and the filter isn't clogged.

I have switched EZL's about and FPR's and it's the same thing. Switched ICU's too.

I fear I have messed up the Mixture ratio while trying to lean out the car.
Is there any PDF's telling how to center the mixture screw so at least I can get the car started.

It is a screw through a spring so in reality it will tighten to a stop at some point.

What I need is the PDF's on this or someone has fixed this problem to chime in with some info.

I promise NEVER to do this stupid thing again, but I need help.
