Oldsmobile Cutlass Carburetor Parts Questions & Experts Answers
- Q: How to tighten the carburetor mounting nuts?A: The carburetor is attached to the top of the intake manifold by two or four nuts. These fasteners can sometimes work loose through normal engine operation and cause a vacuum leak. To properly tighten the carburetor mounting nuts, a torque wrench is necessary. If you do not own one, they can usually be rented on a daily basis. Remove the air cleaner assembly, tagging each hose to be disconnected with a piece of numbered tape to make reassembly easier. Locate the mounting nuts at the base of the carburetor. Decide what special tools or adapters will be necessary, if any, to tighten the nuts with a properly sized socket and the torque wrench. Tighten the nuts to a torque of about 12 ft-lbs. Do not overtighten the nuts, as this may cause the threads to strip. If you suspect a vacuum leak exists at the bottom of the carburetor, get a length of spare hose about the diameter of fuel hose. Start the engine and place one end of the hose next to your ear as you probe around the base of the carburetor with the other end. You will be able to hear a hissing sound if a leak exists. A soapy water solution brushed around the suspect area can also be used to pinpoint pressure leaks. If, after the nuts are properly tightened, a vacuum leak still exists, the carburetor must be removed and a new gasket used. After tightening nuts, reinstall the air cleaner, connecting all hoses to their original positions.
