- I have a 1976 Chevy Malibu SW that needs a carb rebuild. I
- have the Chilton manual, and have tried to determine from the pictures
- in the manual which carb I have. (The manual covers all Chevy midsize
- from 1964-1988!!) It says that the carb should be labeled, but I
- can't find a label or number anywhere on the #@$& thing! From what
- the manual says I think it's either a Rochester 2GV (2-bbl) or a
- Rochester M4MC (4-bbl)
-
- My question: Is there a simple way to tell which one of there
- carbs it is? Can you tell if a carb is a 4-bbl just by looking? If
- anyone out there has this car, or a 1976 Chevy vehicle with the 350
- V8, can you tell me the difference, or what yours has, and what it
- looks like?
-
- Looking down from above, the two bbl carb has two large openings, one
- along side the other. The four bbl has four, two large openings side
- by side and another pair of smaller openings in front of them.

- The BEST way to find out which carburetor you have is to look for
- its identification number. You can often find it without removing
- the carburetor but you'll probably need to clean off a few years
- worth of gunk from the outside first. I use an old toothbrush and
- a can of carburetor cleaner. The number is usually stamped into the
- main casting. A mirror may help you find it.
-
- I don't mean to flame you Scot, but if you are having trouble with
- something as basic as this, then perhaps rebuilding your own carburetor
- is beyond your present skill level. If you are determined to go
- forward with this plan then I strongly suggest that you enlist the
- aid of someone who has done this kind of work before.
