If you have a B&S vertical shaft 210000 or 310000 engine, we have the air filter for it. Our air filter (695547, 697153, 697014, 697634, 697776) for Briggs & Stratton 210000 and 310000 engines will fit fine on those models made in 2010 or after. These little gas engines provided the power for thousands of lawn mowers and other applications.
