    IF, if, if, my guess/assumption is correct, you have a blocked bowl vent.  As fuel enters the bowl, the level rises and shuts the needle valve.  But it can’t rise because of the air bubble above it.  Therefor since it can’t rise, it doesn’t close the inlet needle and just continues to flow in and up and out the high speed nozzle.  BTW, congratulations on your thinking.  You almost got it right.

    If my assumption of a blocked vent is wrong, then I dunno.
