Carb is running too rich!

[ilikeike]

Turning idle mixture screws all the way in/lean and it’s still running still seem like your throttle plates are open too far and your running off the main circuit.
You might need to adjust idle or hi speed air bleeds and or the idle feed restrictor jets.

You never know what you’re going to get or what the last guy screwed up when you buy a used carb.

Familiarize yourself with the Holley, this book will help.
Good luck.
