Thanks for all the responses. The carb seems to work fine, it's the choke that's the problem. When I set it so it closes when cold, it won't open far enough when warm, and when I set it open when the engine is hot, it won't close when it gets cold. The spring seems to be ok, and it opens and closes partially, but not far enough. Maybe I'll look for a new or different spring.
Thanks again for all the good thoughts and info.
