CARB talk!
When I had Edelbrock I had a some of the same problems with it you are. What motor is this a 360? Does it have a choke? If you get the engine warm does the dying problem go away? Sounds like you have the eninge at TDC if its a 360 try getting it to atleast 10deg advanced. Also I think Edel carbs only want 5psi of gas.
