I figured it out. Thanks for your help. If nothing else comes from this , at least I learned how much of an idiot I am.
When I installed the carb I pinched a spark plug wire with the back end of the carb. The cable was completely cut in half but still smashed inbetween the carb and instake. This was causing a misfire in cylinder #7 and preventing the carb from seating correctly in that back corner.
