Default YS-FZ110 dies on idle only in flight

My YS-110 runs smooth and powerful. No problem on ground checks at all RPM. Throttle transition is also good.
In flight ferformance is also very good however, when closing to idle for landing, it will die.
One thing I've noticed is considerable air bubbles when throttle in idle position in the fuel line from the air chamber to the engine intake. Is this normal?

Would appreciate any tip

Those bubbles are normal and actually the reason why YS went to a dark blue tube from the regulator to the carb.

When you start the engine on the stand what is the idle RPM and how long will it hold the idle? What plug and fuel are you using?
