I have two Zenith 35/40 INAT carbuetors to rebuild. While disassembling the first one, I had no problem until I tried to seperate the top section from the float boal section. I have re, re, re confirmed that I have removed all the screws, but they will not come apart? I tried using a little extra force by tapping a flat blade screw driver inbetween, and lightly prying...did not work. I am real hesitant to pry harder and possibly break the sections. Is there some trick to seperating these sections? Thank you in advance.

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.
