74 Dart 318 BBD carburetor

To start I don't know all the nomenclature so here it goes.
My 74 turns over easy. but does not start. I primed the carb and it fires then
dies. I pulled the fuel line, and it is getting fuel.
I pulled the that small cover in front the barrel, it seems this is the "power valve"
Please correct me I'f I'm wrong.
So I poured some gas into the area and it just drains away...
I did this 2 or 3 times. I don't know much about if anything about these BBD Carbs
so enlighten me..
Best
