Coleman Powermate 5000 Generator Carburetor Replacement

Hello... I have a Coleman Powermate 5000 Generator, which I purchased about 8 years ago...  I haven't used it for a few years now, and, of course, it won't start.. I determined that the carburetor needs cleaning or replacement. My problem is, I cannot get it off the engine... I removed the two nuts that are attached to two bolts that run through the carburetor and air filter housing, and removed the air filter housing, but the carburetor is still attached. I do not see any other bolts holding it... Does anybody know how to remove this carburetor ????  Thank you
