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. >I tried adjusting the mixture screw because I > am sure it had already been tampered with but couldn't get the mixture screw > to budge... I snapped my hex key trying. Now I need to figure out how to get > the head of the hex key out of there. 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.
