Where is the adjustment screw located on a 93 Oldsmobile cutlass supreme carburetor?

The location of the adjustment screws on a 1993 Oldsmobile Cutlass Supreme carburetor depends heavily on the *specific* carburetor model. There's no single answer. Oldsmobiles of that era could have used various Rochester, Carter, or other brands of carburetors.

To find the adjustment screws, you'll need to:

1. Identify your carburetor: Look for markings on the carburetor body itself. This will tell you the manufacturer and model number.

2. Consult a carburetor repair manual: Once you know the make and model, find a repair manual specific to that carburetor. These manuals will have diagrams showing the locations of the idle mixture screws (often two, one for each barrel) and possibly a fast idle cam adjustment screw. Online resources like Haynes or Chilton manuals, or even eBay listings for the same carburetor, might have images.

3. Look for small screws: The adjustment screws are usually small, often brass or Phillips head, and are typically found near the base of the carburetor, close to the throttle linkage. They might be hidden under a small cover. Be cautious: These screws are very sensitive and improper adjustment can severely affect engine performance and fuel economy.

Without knowing the specific carburetor model, giving a precise location is impossible. Attempting to adjust them without proper knowledge is risky and could damage your engine.
