John,
I disconnected the vacuum line from the vacuum advance can and plugged it. Although, I will say, that with the timing light on,and the line plugged, the timing mark did move counterclockwise upon acceleration but it came back to where it was at idle. I suppose the timing would still move upon throttle even with the line plugged?
You asked once about whether the idle speeds up when disconnecting\plugging the line. I can't hear any difference in idle when I do this. The line is connected to the one and only port on the Rochester carb. Do you think maybe I need this vacuum line elsewhere?
Thanks
