Hey, I was fixing dinner and had an idea what the problem might be, so dropped everything to post this.
One of my bikes had a problem with a float bowl overflowing and it drove me nuts. The float was set properly and turned off at the correct place, but then one time while taking a closer look, it seemed like the float needle was getting stuck.
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.
