Fuel is still not going through the carburetor in enough quantity to keep engine running. Did you look at the needle valve ? Was it an all metal needle, or a needle with a rubber tip. All metal needle has a rubber seat in the upper housing, and this rubber can swell, closing the hole , from ethanol swelling the rubber. It may be restricting the flow of fuel into the bowl.
If it was black, it has rubber tip. So it has no seat to swell. But the passage could be plugged with debris, or the main jet in the center of the carburetr, where the bowl bolt goes, can be plugged.
I see question is still open, did you get it going?
