Initial timing

Steve you said at idle it went up with ported vac connected to the VA?. if there is any vac at all at idle out of the ported vac you have to take care of it first. Also you mighty vac'd the VA you said it was good. It is adjustable for rate only not total, look into that all first like we talked about. Ohm out he pick up it is probably fine do it hot and cold. From what I am reading it sounds like when the VA is hooked up it advances and stumbled which makes sense am I right? If so double check you have zero vac on the poted vac port and if there is adjust the throttle blades.
