If you will look at the dist advance charts in the Bentley you will see that there is a kind of dual slope arrangement to the late dists. This is due to the fact that they have 2 different springs and the second spring doesn't come into play until after a certain amount of advance has come in. You will notice that one of your springs is "loose" when at rest. This is the way it is supposed to be. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
