Lawn Boy 680529 slow with more throttle

I've got a Lawn Boy model 680529, that hasn't been running well lately. It starts ok, but when you give it more throttle, it runs worse. It runs best about 1/2 to 2/3 throttle. Also, after it warms up, it tends to run worse, to the point that it won't start after it's been running and you shut it off.

I checked the exhaust ports, and they were ok. I took the carb off, cleaned everything, and blew out the seat with compressed air. It's still running poorly. Governor seems to be working ok.

Any ideas are appreciated.
