You have seepage from the pump side of the carb past the needle and seat of the metering valve into the metering chamber of the carb.

In other words, the metering needle is not holding. This could be caused by a stiff metering diaphragm?

You may try to tighten the plug to see if it stops the leak but I doubt that is your problem?
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
