how do i find the carburetor in a 1992 lumina

Hello, For some great diagrams on this, I direct you to http://www.autozone.com. I cannot give you a full link, unfortunately, because it is a cookie-run site. Once you get there, go to "Repair Info," enter your car as the current vehicle, click "Repair Info" again, then "Repair Guides." It has some excellent information. Best of luck! CarGrrl
