How do I adjust my Qaudrajet Carburetor for my ‘82 Firebird with a 305?
I’m only looking for a basic adjustment…I don’t know anything about carbs so I can’t do that advanced stuff. I just need to know how to adjust the 2 screws in the front which I am guessing controls how rich or lean the mixture is. I’m sure I only need a screwdriver, but maybe I need something else. If you have any other basic tips for me that will help it run better, please let me know. Thanks a lot guys.
Those are supposed to be sealed, but I suppose someone broke the caps off. They control the mixture strength on the primaries. The right way to adjust them is to tune everything else up first: distributor, wires, plugs, idle RPM, all perfect. Then use an exhaust analyzer to get the air mixture to 14.7:1 by adjusting the two screws equally, a little at a time. If the idle speed has changed, adjust and do it again until everything converges.
Before pollution control, we’d adjust them by ear. Usually this meant turning them in until they seated (gently), then backing out each screw two and a half turns. Then, one at a time, you would adjust a screw until RPM was maximized, then back it down to the “lean roll” position…where the engine just starts running rough. Then turn it back up about half a turn, to where it felt smooth and sounded “right”.

Safety Tips to Building a Computer
There are some important precautions you should take into account when building a computer to ensure the safety of you and your computer parts. This article gives you some helpful tips on building your computer in the safest way possible.
Stay Safe With Electricity
Electricity is an important issue to consider with dangerous implications for those who ignore it. When building your computer, be 100% sure that the power supply is disconnected from the mains. Also make sure that all network cables and telephone lines are disconnected from the computer.
Another electricity safety tip is to only turn the power on to your computer when the case cover is on. Don’t ever work on the inside of your computer with the power plugged in and turned on.
Be Aware of Static Electricity
Static electricity is a real hazard than can cause significant damage to your computer components. To prevent this from happening, follow these simple tips:
- Always wear an antistatic wrist band when building your computer.
- Keep sensitive components in the antistatic bags that they came with, and only remove them from the bag when you are ready to install that component.
- Try to handle your computer components by their edges only.
- Avoid building your computer in areas of high static such as carpeted areas. If you can, try to avoid wearing clothing such as those made of synthetics as they may create static.
Use the Right Tools for the Job
These days, building a computer doesn’t require many tools at all. But if you’re going to be using a tool, make sure you use the right one for the job. Some tools that you may need for assembly are:
- Phillips screwdriver
- Flat nose screwdriver
- Pliers
- Antistatic wrist band (highly recommended)
- Nut driver (optional)
Conclusion
After reading this article you should now be aware of the main safety issues you need to consider when building a computer. Follow this advice and you will greatly reduce the risk of damaging your computer, or yourself.
