When you cleaned the carburetor, did you remove the needle from the unit? Was the needle solid metal, no rubber tip? With all metal needle, there will be a rubber seat, in the upper needle valve passage. I have seen this seat swell up from ethanol , and plug the opening, so no or very little fuel gets to the carburetor bowl.
Repair is to replace the needle and seat.
