1982 CB650 Carb question - wrong parts?

I took my carbs to a shop to get cleaned up and after they dissassembled them, told me it would be about $400 to fix. I bought the bike for only $500 so figured it wasn't worth it and I could learn to rebuild the carbs myself (have done a few holley 4bbl carbs before). What got me is they said they had some wrong parts in the carbs which threw me off. Would a carb kit have all the correct parts I should need in order to rebuild these carbs? The bike ran for a while but started leaking gas from the carbs hence the rebuild so I would think the "wrong" parts can't be that bad.

If you order the correct kits for your bike (they are bike-specific), you should have no problem and they really aren't all that expensive. They should come with all the parts you need to put everything right. Most of what the shop was charging is for labor. I have no idea what they meant by "wrong parts."
What probably happened is some trash or junk got into the float valve(s) preventing it from seating correctly. Hence the overflow. Make sure there is no rust or debris in the tank or fuel lines before you connect everything back up, or else the same thing may happen again.

Before ordering the kits....... your main problem may just be needles and seats. If needle and seat has debris stuck or if needle and seat are damaged then cleaning or replacement will be required. You may not need all four. Pull the bowls off, send some fuel through and hold up the float to find the culprit. As long as the o-rings and gasket are not hardened or cracked you can reuse them. Float height should be parallel to carb body for correct adjustment(before centre plunger in needle is depressed).
I think most needle/seat assemblies are expensive, they might have quoted to replace all four.
