I have this Rochester 4GC "4 Jet" carb with number 7026941 cast on bottom of the body...at least I think the "9" is a "9", since it's a little disfigured. I've researched the lists of the carb I.D. numbers, but can't find this number or a one real close to it, to identify the application. The closest number I've found to my number is 7026040 and is for Buick. I've seen a couple of pictures of it in my searching which also point to Buick, and maybe Pontiac, from around 64-66.
So, I was hoping that you Buick experts might recognize it, and can tell me what year, car and engine this carb is for from these photos. Thanks, Steve

 

You're kinda pooched without a part number. Fortunately, Tecumseh may have a large number of different carbs, but most look completely different. Google a tecumseh replacement carb and try to find one that looks as close as possible to get a part number.
