I try to avoid ethanol in my small engines even in those supposedly designed for it. It's a powerful solvent and a potential troublemaker in my experience.

Disconnect fuel line from carburetor. Remove bowl on bottom of carburetor by removing nut. Carefully, remove the pin from the float and it will come off along with the fuel needle. Then just put back together. Do this outside because you will spill a bit of gas and it will stink until it dries out.
