Except that overflow doesn't pass through the bowls on my carb. I often hear sounds from the overflow but with this most recent episode I have absolutely confirmed that there is boiling occurring in the bowls.

Assuming the fuel is in fact boiling, couldn't the spewing and sputtering occur even with a properly functioning needle and seat? As the fuel boils off in the form of vapor or pressurized squirts the floats will drop and allow the passage of more fuel. So I'm thinking that even with a functioning N&S this problem isn't going away until I reduce transfer of heat to the carburetor?

Thoughts?

And, Mikael, I agree 100% that I should start with the simple inexpensive stuff. That's why I'm starting with N&S and spacer.
