How to read carb calibration chart?

Are we to assume this is an automatic transmission car? If so, how much of a drop when you put it in gear? If it's more than about 100 RPM or so, it needs more initial timing. That's the first thing you should rule out before anything else. I saw you said it has 17 initial, but some need more. Also, I think the Autolites are good plugs. Are you 100% SURE on that static compression ratio? Seems like 17* initial is a lot for that. You "should" have problems with spark knock if it has iron heads. If not, I question the compression ratio. Is it MEASURED or is that just what someone "said"?
