I took a trip to a local junk yard yesterday and pulled open a few Bosch air/fuel mix units. I discovered that regardless of the specific Jetronic unit the internal CO2 adjustment screws were identical. I pulled two from a Mercedes 560SeL and a 1986 VW Cabriolet that were identical, given that they were very different in size externally perhaps the internals are fairly interchangeable. Also I was able to screw the adjustment screw in all of the way and remove it without removing the rocker arm. Hope that helps others, also I now have an extra that is in fairly good shape if anyone needs it please contact offline.
