69 340 AVS fuel leak

I swapped the needles, seats and floats side to side, and I still have the same problem, fuel leaking down the passenger side secondary tube after shutting off a hot motor. There is still that gurgling sound coming from the carb after shutting down the motor, and removing the fuel line does NOT stop the leaking or gurgling. I also quickly removed the top of the carb while still hot, and I could see bubbles coming from the primary jets on the floor of the carb. I think that swapping the needles, seats and floats proves that they are not causing the problem. Is this considered "normal" for the Carter AVS? Has anyone experienced this before? Any other advice would be appreciated.

You don't see fuel from the venturi's while idling because the fuel is fed through the idle circuit, not the main circuit.


Redfish: did you ever completely remove the fuel baffles in the carb? What effect would that have?
