Idles fine, but once revved stays revved

The throttle connection on the carburetor seems to return to normal. If I shut it off, it starts up fine and idles again. If I drive it and mechanically slow it down, then it stays down. Could it be the piston has gotten stuck? I removed the carb and attempted to clean it, but haven't done the Chem Dip thing yet. A gallon is $30. Would that likely fix it?

I feel like it is running lean when in this state. While at idle, it smokes some suggesting rich.

I tried spraying carb cleaner on the intake header but the idle didn't change.

I just added SeaFoam to the tank, we'll see if that helps.

Any tips appreciated and I promise to report results. At what point do I order a new carburetor? Is there a good aftermarket carb someone could point me to?
