My original post was in error. After looking harder, I found that there is a screw in located approximately in the center of the carburetor that is recessed so far into the carburetor that I could not see it. I tried using a small flat screwdriver to see if there was anything in there...to my surprise there was a flat head screw in there. After removing it, the carburetor fell apart. I feel stupid, but if this post helps someone else in a similar situation...it is worth it.
