Edelbrock setup for dual quad

Hello, my name is Joe, and I own/run an engine dyno. I have done dozens of duel 4 barrels. 1st, don't worry about the secondaries, they will never open, unless you get to 5500. 2nd, all Edelbrock carbs are rich out of the box. 3rd get a a/f gage if you want to dial it in right, it will be quicker, and you will be a lot happier. Unless you like pulling a plug every 10 mins.
If it doesn't idle unless the idle mixture screws are way out, look for a vacuum leak by spraying carb cleaner on the head mating surface. Without data, everyone is just guessing.
PS Edelbrock carbs are so nice when they are dialed in!
