Any water in gas with ethanol will bum you out. That goo is evil.
I mentioned to Ray that I honestly don't remember if I dried the tank after the first wash. Maybe there's some water in the gas causing the issue? Probably also has gunk in the jets too though. I shall see tomorrow.
I'd clean out everything in the fuel supply from the tap to the jets before jet-chasing that possibility.
There's a range where jetting "should" work on a given setup. If it doesn't, it's usually fuel supply or an air leak.
