Carb help for Newbie,plaease!

Hello, have a Holley 4 barrel carb older model. The car will start and idle fine but as soon as I rev it up then it idles super fast. It wont kick down or anything. It is also kind of backfire and popping. I have checked for vacuum leaks and messed with the accelerator pump adjustment. Kinda of at a loss. Any help would be greatly appreciated. Thanks
