How do you adjust the carburetor on my 83 buick regal limited 4.1L-v6

SOURCE: Buick Regal 3.8 dies while braking

Check to see if you have a lot of dirt in the throttle body. Clean the throttle blades out with brake cleaner or throttle body cleaner. You'll see alot of dirt come out. Keep spraying until it comes out fairly clear and wipe the throttle body out with a rag. If this doesn't do it, you may have a problem with the throttle position sensor (TPS). This sensor controls the idle after the car warms up and keeps it from dying when you brake or sit at idle.

SOURCE: Need Cylinder head bolt torque specs and sequence

1. Install the cylinder head gasket. Ensure the arrows point towards the front of the engine. The left cylinder head gasket has the letter L stamped next to the arrow.
   
2. Notice
3. This bolt is designed to permanently stretch when tightened. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.
   
   
4. Install the cylinder head.
5. Install new cylinder head bolts. Tighten
   Tighten the cylinder head bolts to 50 N·m (37 lb ft) in sequence.
   
6. Use the J 36660-A to rotate each cylinder head bolt 120 degrees in sequence. Use the J 36660-A to rotate the four center cylinder head bolts an additional 30 degrees in sequence. Refer to Notice Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
   
   

SOURCE: buick regal 92 3.8L Horrible fuel mileage

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
