Did you get this guy when you cleaned the carburetor? That is the Pilot Jet, and it lives at the bottom of that jet tower. This Jet feeds the fuel at idle.

The fuel available to us is terrible. Some say the Ethanol fuel blends begin phase separation and breakdown in as little as three days from purchase. The predicted shelf life by the distributors is 90 days under ideal situations. A metal tank subject to temperature fluctuations, producing condensation, is less than ideal. Alcohol mixes with condensation, speeding the separation of gas from alcohol. Soon, you have a corrosive fuel, and the chemicals used to prevent the separation are contributing to the blockage of your carburetor. These additives are new to us, and the method of removing the blockage they generate is all trial and error. I haven't found any one cleaning chemical that gets it all, every time. It's not unusual to have to go into the carburetor two or three times using different chemicals to clean everything out,
Best of luck, and welcome to the forum.
