Or, I can adjust the choke to open fully when the engine is warm, but then it won't close fully when then engine is cold. I have owned about 20 different carbureted vehicles - same story with each one, regardless of the type of automatic choke. So, I now use only manual chokes.
I would call this experience, not personal opinion, but each to his or her own.
Not sure why you have the choke wired open if it is functioning properly.
