The choke does close all the way. But as far as I understand, a choke closed all the way stalls the engine, so I'm not sure how that would be connected. And yes, the idle screw is almost screwed in all the way. I never touched it. That's just where it lands when the engine idles at about 500 rpms. I have noticed it, though, and think it's a little weird.
