It's virtually always a mistake. I have adjusted a few of them, but it was in the dealership with the proper equipment. This include a FI test system, (not the VW EFI Testor) and a calibrated CO meter. It was very seldom that they needed adjusted, and it was only under special circumstances that we did it. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
