From TBI to Carb.

I need help in finding out what I need to do to swap out my TBI and put in a carb. system. I need to know what I need and what I need to do so that I can make this process as short as possible so that I will not be without a vehicle for too long. I would really appreciate the help and if anyone is selling anything that could help me on my quest I would be much abliged if they would offer it to me.

The reason I am getting rid of the TBI is because on startup the car seems to die alot and I just cant keep it running. It has nothing to do with the weather. I just cant explain why my car does this. If someone could tell me how to fix this I would gladly take their advice and most likely fix it I just have no idea as to what it could be. Please help my guess its embarassing having a car that I need to baby on startup and can not just go or it will die. Once the car warms up it runs like a dream. I need help.

There is 185000 miles on the car and I do not believe that the motor is the original. The previous owner said that he did a tune up but you know how used car people do as much as possible to make the car more appealing? Do you have any idea of someone that could answer it for sure I mean I totally believe in what you are saying I just want more than one person to say that thats probably what it is before I spend that kind of money on fuel injectors.
