CARB JETTING SUGGESTIONS

Thanks for the welcome aboard and the compliments on my car! I'm already glad I joined this board for the info and feedback i'm getting. I wish I could hook up a vacume guage but my carb doesnt have a port! I bought the carb from Ray Barton and I guess he sources them from a guy named Gary Williams. The carb was originally built to specs for the stroker engine I had in the Duster, I've been trying to settle it down for a while now and thats why I'm running into trouble.
