I think the problem most often arises when there is a problem and the first thought is to adjust the PS. Now we have a problem AND a misadjusted PS. People who trouble shoot like this are then apt to readjust the fuel pressure, so they now have a problem, a misadjusted PS AND the wrong fuel pressure, and so on. Pretty soon we forget all the things we have changed and have no hope of ever finding our way back. If it were all just a matter of ONE screw, then I would agree with you completely, but it never is. Plus the problem with this screw is that we have no instructions as to how to get it adjusted right again. While we can make intelligent guesses, that's all they will ever be. So often the problem is something simple that will be found if we just go thru all the basic tuneup and troubleshooting stages. If those don't help, then the only real answer to suspected problems with the brain or PS is to try a different part and see if that changes anything. Mark Fuhriman's trials should be an inspiration to us all as to how these things can be traced down eventually. Luis discovered amazing things about the poor quality of non-Bosch injectors and the importance of a properly working mechanical advance. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
