You have been running rich. There's no need to choke an engine after it starts.

You're going to have to check the basics. Make sure your timing is correct.

Set the octane selector on the dizzy to "0" and then make sure the BB on the flywheel is at the pointer.

The mixture screw on your carburetor should be adjusted out about 1 1/2 turns.
