yeah, I checked tdc back when I had the heads off and it was dead on with the balancer. I'm using an edelbrock 650 mechanical secondary and mechanical choke. I set the timing with a light and found it idled best at 15 degrees static. I'm using the manifold vacuum for the advance.

There was never any popping back when it was warm out. I just heard some popping coming out the exhaust when it fired up and then a little during warm up. I think my idle was super lean though since I had last set it in summer and it was even a little lean in summer too from when I once looked at the plugs.

It wouldn't even idle with no choke until I gave both idle mixture screws a full turn richer.
