I also recomend getting one or two of these
"CARBURETOR ADJSTING TOOL"
They can be found in the isle at any checker or autozone. They run anywhere from $5 to $20 each. I bought (2) and they were about $6 each. The long shaft is flexable to get around parts and work between vacuum lines. They come with different bits for different carbs. I recommend getting two of them because you can hook one to each mixture screw and keep good track of each turn. When you have to take the tool off and on to go back and forth its not as easy to keep track or the turns and its a hassle.
Save your self the headache and get two of them.
