This is a follow-up question to my previous question. I have posted my previous question below, but have since taken the car to a repair shop. They have informed me I am in need of a carburetor rebuild, which will cost $600. I have done the research, and I know a rebuild kit is only about $20. It seems pretty simple to rebuild the carburetor; take it apart, clean it with carb cleaner, and remember how to put it all back together. Is this all that needs to be done, or are there other things, such as adjustments, tunings, etc? Would it be wise to buy a new float?

Here is my previous question:
My 1982 Impala stalled while I was making a sharp left only. It did not stall while turning right. The check engine light has been on since I purchased the car about a month ago and it has been driving fine. When the car stalled the choke/oil light and battery light came on. Any ideas on what this could be?

Carb kits vary in price. But when you buy a rebuilt one there is markup on the carb that they pay for as well as labor for installation and adjustments. You carb has a few electrical devices in it for choke, and acceleration. There are also controls for emission, not many but still there are adjustments to be made. Even if yo u look at carbs on the market today like Edebrock, HOlley, etc they run hundreds of dollars as well and that is without adjustments or installation. If they are quoting you is one that has already been rebuilt and has all updated stuff inside. Your car is 30 yrs old and quite a bit has changed in that time span. Prices vary all over so if you aren't satisfied with it then check around you may be able to get a cheaper quote.

If I were to buy a rebuild kit to do it myself is it difficult?

Carb overhaul kits normally come with instruction on how to set float levels etc. But you need to adjust it after it is put on the car an dis no guarantee that it will work ok. In your case you have to check the float to see if it's not been eaten out inside so it doesn't work anymore. I'm assuming it'a 4barrel carb and rochesters always had vacuum leaks between the pieces of carb. If you are mechanically inclined then maybe but if not don't try it. Also in a rebuild kit there will be pieces that you won' t get in the kit. So if you do tackle it try nto to lose anything nor damage anything. Also get a very thin piece of wire to run through some of the small holes etc. And do a good job of cleaning it. Power block tv and magazine has a very good article on how to rebuild these step by step and what things to do to stop the vacuum leaks. It's free, you'll just have to go back through the magazines to findthe article and print it out. If this is a daily driver then spend the money. If it's a toy then go ahead. Just follow the instructions, pay attention and take your time. And if the float sinks in gasoline then you'll need another they should float. You'll hve to leave it there for at least 10 minutes.

Thanks! It is a daily driver so it probably wouldn't be best for me to try my first rebuild on it!
