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

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
