Holley 750 DP, Flooding on startup

My truck has a built 350 SBC. It did have an Edelbrock 650 on it, but now it has a Holley 750 double pumper, it is manual choke with a pull out cable.

The truck runs great, and much better with the Holley.

The issue I'm having is on cold starts I keep flooding it. I assume when I pump the pedal I'm putting too much gas in it with this bigger carb.

Should I try not pushing the pedal all the way to the floor? Maybe just pull the choke out half way only, and pump just half way?

I'm just looking for some tips with this. As I said the truck runs great out on the street, so I don't think I have any carb problems, I just can't seem to figure out the best way to operate the choke on start up with this new carb.

Thanks guys.
