fuel leaking from holley carb after shutdown

hum, what am I missing here. too high, should be at the bottom

It has the large sight glasses. AED says that is where they prefer the fuel level. When they told me this, I was discussing things in general with them when I bought the carb, not about the issue I am having. May not be working for my application though. Maybe I should try the insulator and lower the level a little.
