wow...im not sure i've ever said this with an engine (at least not that I'd admit in public)...I'm Stumped...I hope someone has an answer because i certainly would like to hear it...i would have gone directly to A) fuel shut off valve B) needle and jet, and C) float level. The float level set too high will let fuel continue into the bowl, but without the vacuum of the engine turning over, the shutoff valve would cover that symptom...have you drained the bowl and then left the drains open to catch fuel over a period of time? A little fuel can sometimes seem like quite a bit...unless you are stuck on the side of the road...I am very curious about the bubbling...
