Just think of the extra lift you'll have this morning
Corky, I too think it's a fuel flow issue, using the choke draws more fuel into the system. Check the complete fuel system from the main jet back to the tank.
One of my tractors had a simular problem it turned out to be crud in the inlet to the fuel strainer. Used a little compressed air (short bursts) in the end of the fuel line. I did this while holding a rag over the filler.
