Suspected problem due to ethanol damage to engine not designed to use it.
1. Drained fuel tank.
2. Removed shroud, air filter assembly and disconnected fuel line. (Good time to replace air filter)
3. Removed carburetor, noting manner of attachment of throttle linkage.
4. Disassembled float bowl from carb.
5. Removed float, needle valve and needle valve seat.
6. Remove old air cleaner gasket.
7. Thoroughly cleaned carb and parts to be reused.
8. Replace needle valve seat per instructions supplied with new part.
9. Replace float and needle valve with new parts.
10. Reassembly float bowl on carb.
11. Reattach carb to engine, including reattachment of throttle linkage.
12. Reinstall fuel line. (Note: I recommend installing an in-line fuel strainer.)
13. Reinstall air filter assembly and shroud.
14. Fill fuel tank
15. Test run engine.
Engine now starts easy and has same power as before.
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.
