Bill, you may have the adjustment needle open to far. If I remember correctly, mine runs at around a quarter turn [or a hair more] from gently seated. There is also a lift spec for the poppet valve… this refers to the amount the poppet valve is allowed to open. There is a cork ”stop” that the poppet valve bumps in to that could also be worn out. At the moment I don’t recall the correct adjustment spec….. Gary will know when he see’s this. It may also be possible to ”lap in” the float needle if it’s not sealing correctly, however, if it’s its grooved to bad it will need replaced.
One other thing I can tell you, is those little carbs have a tiny fuel passage after fuel leaves the bowl, then travels through the passage exiting the carb from a tiny hole when the poppet valve opens. Clean with carb spray followed by compressed air to be sure their open.
