Briggs WMB is an old model of small gasoline engine produced by Briggs & Stratton, a manufacturer of small engines for various applications such as lawn mowers, generators, and other outdoor power equipment. The WMB model was first introduced in the 1940s and was used in various types of equipment, including washing machines and lawn mowers.

The Briggs WMB engine is a single-cylinder, four-stroke engine with a displacement of 21 cubic inches (or 344 cc). It has a horizontal shaft and is air-cooled, with a cooling fan located on the flywheel. The engine is equipped with a manual recoil starter, and it can produce up to 3.5 horsepower at 3,600 rpm.

Due to its age, the Briggs WMB engine may not be as efficient or reliable as newer engines. However, it has a simple and rugged design that can make it easy to repair and maintain. It can still be found in use in some older equipment and can be a good option for those who prefer working with older machinery or those who appreciate the history and craftsmanship of vintage engines.
