Weber Engine Cut Off

I started to experience an issue with cold starting. When the engine turns over it starts up and idles fine, but once I give it gas the engine will die. Any ideas?

Check your fuel pressure, float levels and accelerator pump volumes.

fuel pressure is at 5psi. If I am going to check the float levels and Acc pump shouldn't I just rebuild/clean them, since they have to be removed?

Isn't the fuel pressure spec for Webers 3.5 psi?

FAR too high; fuel pressure MUST be 3.5 psi for Webers. Once you adjust that, reset all your float levels.
