I never had THAT much advance... at the time I was running a stock 71 FI system and set the timing at stock... I had knocking and pinging when I got into a bad tank of gas... I finally found I could no longer run 87 octane in the stock square or it would knock on the highway at speed... even under moderate throttle. I seem to have had no damage... that was 10 years ago and about 70Kmi ago, but knocking in our motors is indeed a very BAD thing!!

Keith is lucky he suffered little or no damage. ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
