Briggs and Stratton brings back fond memories of go carts and mini bikes as a teenager. B&S engine use a diaphragm on the carburator that after a while becomes dried out and stiff and I would suspect that's your problem. Search for "briggs and stratton diaphragm replacement" on youtube and see if there is a how-to that's similar to your model of engine. Good Luck!
