Don't mind me too much... Just a newbie carb question...

[ixei]

Engine in question is a 396 with an edelbrock intake manifold and carb that has an electric choke.

I've read for hours now on proper technique.
Issue is that on a cold start or most starts that she turns over then dies slowly within 5 seconds.

I currently with key off push pedal to floor once.
Let off completely and turn the key to start.

I can keep it alive if I physically keep gas with the pedal but idle drops off and dies if I let off.
I'm sensing no fast idle.

It will continue to do this if I just drive at every stop until at operating temp.

Where do I begin?
And thank yall
