Ok guys I have a 69 firebird with a '72 400....go figure. Anyway I just had the carb rebuilt and I am running into cold starting delays. When the car is cold it turns over a few times before it grabs. Once the car is warm it will start right up. If it sits for about 45 minutes, it takes a while to crank again. Not sure if this could be the fuel pump or something more serious like blown rings leaking oil. Let me know if you have any ideas. Thanks for the help.
