Never, I said NEVER do a second procedure that isn't necessary when you rebuild something. You make it more difficult to figure out the problem, if there is a problem after the rebuild.
Adjust the throttle linkage according to the factory service manual (FSM), and also do the mixture screws the same way. Then start the car, and adjust the carburetor idle adjustment by screwing it down until you have the correct factory idle setting. You will need a dwell / tachometer for this. The only way to know the engine speed is with the tachometer. Once you have that done, turn the car off, and if it continues to "run" after you turn the key off, or backfires, then you need to reset your timing. There is a specific set of instructions on setting the timing in the FSM. It is my guess that you have the timing way out of adjustment. If necessary, you might have to start at ground zero, by finding top dead center (TDC) on number one cylinder, and then manually set the distributor by turning it until the rotor is directly under number 1 cylinder.
I learned these lessons when I was about 12 years old, when I made mistakes, and had to have an old guy (22 or so) come and help me. My first lesson was what I started this reply with. You will learn the hard way that what you think is simple, is only simple when you understand why. Good luck, and hopefully it will work out well for you.. the old grumpy junkman

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
