lol corey....
that centre screw controls the idle speed, so i need you to up the idle so it will idle by itself.
once you can get the bike to idle, start it and let it run,
now grab some wd40, crc or degreaser and spray some on the join where the carby meets the manifold,
and where the manifold meets the head, and sometimes on the join in the carby where the fuel bowl joins to the main body,
if the idle changes in any way, it has a vacuum leak there
