If your good on fuel injection think of it this way, the choke is your cold start enrichment.Start with the basic setting available for your carb at holley .com then from there a tighter choke means more enrichment longer looser is just the opposite.Tinker with the setting till it does what you need.

I never use a choke, it is the first thing eliminated from my carbs when I buy them. The electric fuel pump is nice because you don't need to wait to fill the bowls, hit the switch wait for the sound of the relief valve going off in the pump and give'r. Yeah I have to hold the engine @ 1500 rpm for a minute or two but after that everything is good to go.
