Ando, #1 - Permatex or similar in the flange gasket area?
#2 These updraft carbs sometimes stumble on throttle up..fine tuning of various things can help here..most often I've found is the teeny holes in between the main butterfly valve might be dirty. I use bread twisty ties to clean these..they are small!!
#3 - Maybe related to #2..airflow problem maybe..they all work together.

The real key we've all found is to do one thing at a time and re-run and try again so you know which thing helped or did not help it run better.
