Sorry, but I don't really know anthing else about the 3rd gen carbs.

Thanks for all your help so far.

The carb i.d. number is on the back of the carb. It usually is a sticker that is silver. It will start with the letter "E". The sticker is on the plate that holds the idle control diaphragm.

Edit- If you describe where that diapragm is at, sure we can put a name to it. I've rebuilt a few of them & have a shematic in front of me.

I'll have to get the name because I did not take it out I can't tell you which part of the carb it came from. This is going to be a big experience, i've never done anything like fixing a carb. I'll try to find out the parts exact name. And thanks for your help so far. If i get it I will PM you for help or post it.
