I noticed I was having this issue this past weekend as well. I agree it may have something to do with the pilot circuit being rich, although it does sound like a lean bog. I’ve pretty much ruled out the main jet and needle since they’re common sizes and slightly on the rich side. The choke knob should only adjust idle, so I wouldn’t suspect that.
