Check the specs on your fuel filter to see how fine the particles (microns) it filters. If it doesn't filter fine enough you could have gotten a tiny particle of crap in some small passage of your carb. Posting more details about your setup, carb, fuel pump, what has been done to car, how long it's been sitting, etc, etc, will help us help you. Either way, I suspect trash in your carb.
