Ported off the carb. I have zero vacuum at idle and it progresses vacuum as RPM increases. Just running it in the garage its just not responsive as it should be and runs rough with no load. I think Ill bump it up to 15 as you suggest and run it down the road tomorrow. Maybe you are into something suggesting initial 15 and limiting the max advance to stop the pinging.

I'm not really looking for a lot of performance, I just want a good running engine. It is crusty looking though. I have had the car (1972 Roadrunner) for over 10 years. Its always been able to move on its own power and is close to being able to drive on the street so that's all I'm really trying to do.
