I would check the flywheel key and see if it has sheared. On push mowers, the key can shear if you plug the deck, or if you hit a solid object like a tree root or stake. The flywheel key sets the ignition timing of the engine, and a sheared one will cause the problems you describe. You will have to remove the shroud and flywheel to check the key. If you don't know how to do this, there should be some basic repair manuals at your local library or online.
A Briggs and Stratton L head twin engine wills pit gas out of the carburetor and flood out when starting if the diaphragm has been damaged. This will cause excessive fuel to enter the carburetor.

Because your carburetor is not getting fuel to the engine - could be a plug in the fuel line or it could be dirt in the screen in the pick up tube in the carburetor. I would suggest you clean the carbutator.
