Does it leak at all when she's running? I'd try tightening up the drain screws, had that happen once, didn't have them tightened up all the way, and she leaked when I shut her off, then the next day she was completely dumping gas everywhere while I was riding, went through 4 gallons in 40 miles, and that was the float needle needing to be cleaned... Since it's when she's shut off, that makes me think it'd be the drain screws or a cracked overflow tube
