The metering valve in the regulator side of your carb is being held open.
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 . . .

The diaphragm is holding the needle and seat open

There are two diaphragms, the metering valve diaphragm and the pump diaphragm

The pump diaphragm mounts directly against the carb body, then the gasket, then the pump cover.

The metering valve, the gasket goes against the carb body, then the diaphragm, then the cover
