Aight Bewy.......

@Bewy I had a little time after we got home from Kitty's dr appointment to mess with it. I pulled in timing until the engine stopped gaining RPM, dropped timing until it lost a little, then pulled in enough to gain that back. We're right back at 23 degrees. Right where I had it. Advance can attached to manifold vacuum shows NO added timing at idle. It is pulling about 6hg at the port at idle. It's just not enough to pull and in the can. The can does add some with RPM. I'm seeing "around" 25-30 extra on top of mechanical at RPM, so the can does work, it just gives nothing at idle. I'll drive it tomorrow and see if there's a difference.
