Mike a bad control pressure regulator will cause the exhaust to run 
excessively rich, destroy gass milage, and misfire according to John 
Hervey's web site.  I'm getting ready to take mine apart and see if 
I can fix it.

My CO2 screw was equally screwed when I finally took it apart.  I 
had to disassemble the mixture unit, remove the rocker, dremel off 
the wide disc at the bottom of the screw inorder to get a pair of 
pliers on it to remove the screw from the arm.  Be careful not to 
twist out the treaded seat that is pressed into the rocker arm, use 
lots of penetrate.  I found that despite the type of bosch fuel 
mixture unit you pull from a junkyard car, that internal screw is 
the same.  I pulled one off of a Mercedes and another off of a 
Volkswagon.  I have a spare if you need it.
