This part is on my Generator, which is a Chicago Electric from Harbor Freight. My Coleman Powermate Generator also has one. It has a linkage attached to the carburetor and also has what appears to be a vacuum line that appears to be attached either to the carburetor or to the block that is between the carburetor and the cylinder head. Pictures are attached. Neither manual that I have nor the parts diagram show this part, or identify it.
Thanks for any and all help,
