Car wont restart after sitting for 5min ???

So a few updates:
*I do have a spacer between manifold and carburetor
*Aluminum edelbrock carb
*Just replaced my ignition box (today)
* leaned out the carb (today)
And everything seems to be working fine now. Not sure what it was, but thank you all. Hopefully it stays this way and I wont have this annoying issue again.
