Upon closer inspection, the sharp edge of the float needle had dug a groove in the brass of the float tang, and was hanging up in that. The float would drop, get stuck down and then not stop the flow. Anymore, I chamfer the edges of those needles to prevent that.
I have succeeded in creating a good mystery when I can stop someone in their tracks with an epiphany!
Funny, I was thinking about that when i pulled the bowl the other night. I cut the fuel the unlatched the bowl and the second I lowered it, fuel dumps all over me and the level of fuel in the bowl was about 3/4 to full. That carb has never leaked but I've almost always noticed the bottom of the bowl having a bit of fuel on the bottom.
I'm going to check that one tomorrow...even if not the cause, that's not a good thing to keep around.
