Well, I advanced the timing a hair on the dizzy and it ran quite a bit better. Advanced some more and with the idle screw turned in it will finally idle so I can get to setting the timing further and the a/f mixture. it does backfire a lot if i stab the throttle but will worry about that after i get the idle timing and mixture set. I just have to read some more on using the vacuum timing method as thats all I have available at the moment.

From what I see so far its set the dizzy at max vacuum then down 1", set idle as low as I can then set mixture to highest stable reading then repeat? How much does the order of the idle and mixture come in to play? Is one better to do first than the other or what is the most reliable order?
