Carter carb tuning help

Thanks alot mark, that made a HUGE difference. I run 93 octane in the cuda and another thing i was wondering is if the hipo 273's use a different head gasket that the 2bbl 273? My compression is a bit low from what i gather. i am getting a consistant 135lbs on each cyl and the engine was just rebuilt so i know things are good. This is one of the best forums for info i have found and i really appreciate all the help guys.
