Quadrajet acting up when cold.

[skokie]

When I first go to start the truck I give the pedal a one stab and it wont fire up. I went out popped the hood, remove the air cleaner and low and behold the choke is almost fully closed. So I go back to the truck hit the gas pedal 3-4 more times and it fires up. Go's to a fast idle of 1200-1300 and its fine. I can drive it for hours and shut up down and it will fire back up. The truck is setup with 5/16 lines and I have a 3/8 L metal line ( about 4-5 inches long) going down to a rubber fuel line which is 4 inches to a metal 5/16 line which is running to the pump and the line to the tank is 5/16. Not sure if that info s needed but hey who knows Any thought on what is causing this? Carb just got rebuilt so I am pretty sure thats not it.

Thanks
