I had an issue one time with my 32-36. It would run for a short time and then flood. I took the 32-36 to a carburetor expert who couldn't find any issue. Finally one night, to my wife's disgust, I took the carburetor apart on our dinning room table! The needle valve had some junk in it, and wouldn't close all the way when the float got to the top. I cleaned the needle valve, bolted it back together and all was well. This may be you issue - just an guess.
