Well, I don't have a choke housing so it didn't come off of that.

I did find a web site that helped even though I didn't buy my kit from them. (very nice of them) They call themselves "The Carburetor Doctor" and the link is

Their response was:
"Very few Thermoquads have one, but it is the gasket for the Hot Idle Compensator. I don't know if yours would have one or not, but if it does it's a bi-metal strip near the secondary air valve. More info here:

I'm leaning toward the thought that it is the hot idle compensator gasket which my carb does not have. I think the last person in my carb placed this gasket in place of the needle /seat gasket but can't remember where I took it off from. After installing the correct needle and seat gaskets and after checking the float adjustments, one float was way different than the other so I thinking even more now that is where it came from because the thickness would alter the float level.
If anyone else has any other theory, I'm open to suggestions, Thanks
