The engine starts easily and will idle with the choke fully closed. If the choke is cut back the engine stalls. If the throttle is opened more the 1/2 way the engine stalls (this is with the choke fully closed).
Any attempt to close the choke will cause it to stall. Also it will stall on its own if it runs for longer than 5 minutes.
The one time the plug was checked after a stall the plug was dry with moderate deep black carbon deposits.
The carburetor was cleaned and rebuilt about 6 months ago. It is a Flo-Jet , medium 2-piece.
I'd appreciate any suggestions as to what to try next.
Hello Ron & Welcome to LMF...
Those old carbs are GREAT...
Here is a good site for cleaning and SETTING the that carb... Disassembly of Briggs and Stratton Medium Two-Piece Flo-jet Carburetor
If anything plugs the small holes in the emulsion tube, you will get what your having... need a lot of choke to pull enough fuel ...
Follow the directions for removing that tube, use a proper fitting screwdriver to reach in and remove the emulsion tube.... clean it out including the cross drilled holes... Tiny flakes of rust can block it...
If this is a continuing problem you may need to put a non restrictive filter or a sediment bowl on the fuel supply...
What is that engine on???
