Need help with edelbrock 1406 carb

Changed the oil yesterday and bought the Edelbrock air cleaner but that’s been yet. Yeah it came on slowly. At idle it started every once in a while having a hiccup. Ran fine when you were pulling away and driving and on the freeway. This morning came home parked for about four hours went with a friend out to lunch and it started doing it then. I just tried doing what trail beast recommended. And it seems to have made a difference. It’s not pissing gas like it was anymore and it starts up at the bump of a key. Let it run for a while and it started hiccuping again and now I see a couple drops in the front barrels after the engine is off I changed the fuel filter as well because I could see some sediment in it.
