Cleanup turns to mess up. Need some help troubleshooting.

Well this is like the 3rd time I've run into this issue. Pulling the carb and reworking it has been the fix the last couple times, but I just rebuilt the carb so im going to disconnect the fuel line and test for spark again and go from there. Tired of messing with this thing already. I've been troubleshooting/fixing things nonstop for the last couple weeks.
