Car will not restart. Fuel on Carb Blades.

I have a 1968 Dart with a 340, the carb's been replaced with an aftermarket holley with manual choke. The car starts up fine if pull the choke. It seems to be forever before I can close it without the car dying. If for some reason I close it too soon the car will not start for quite a while after. I do notice fuel on the blades of the carb immediately after shutting down.

What should I adjust to solve this?

Thanks
