ping at high speed or foot to the floor
Thanks for the advice. I have tried the "timed" passenger port and the "mainold vacuum" driver side front port and they both ping. I am going to back the initial plus mechanical down from 34* to 31*. If I get no ping in a test run with the vacuum advance disconnected I will try with it connected and if I get a ping I can always turn the canister down a half a turn. Also, I am running fresh gas and a new fuel filter.
