Okay so here's where I'm at now...

I replaced the cap and rotor again because of half inch long arc marks on the leading side of each post, with no change in how it runs. Because the marks are on the leading side it seemed logical that my timing was way advanced, but is dead on 5btdc at idle. I went back in the dizzy to see if I missed something, and thought maybe one of the springs was maybe getting weak, one had a little play in it, so I doubled up on it to see what would happen, no change. Then I decided to check the timing at high rpms, which I hadn't done yet, and wow, with the vacuum advance hooked up it was going well over 30, more like 40btdc. With the vacuum advance disconnected it went right to 28, but well before 6000 rpms. I'm thinking I have a vacuum problem, like the retard is switching to advance to soon, but what would make that happen? It switches back and forth fine when throttling up and down, but what rpm should it happen at? I haven't seen that info anywhere.

For now I'm just running with the advance disconnected hoping someone will have an "ah-ha" moment. It doesn't have the power it used to and has a slight hiccup at low rpms, but it's better than not driving it at all!

Steve.
