BRIGGS & STRATTON MODEL 5S 2.00" bore 1.50" stroke

The model 5 and 5Sare updated versions of the WMB with an improved suction feed carburetor on the 5s version and a deep oil sump. It is belived that this engine was developed for power lawnmowers with the deep sump improving in non-level enviroments. The WMB had a very small oil capacity and would burn up if operated off level. The 5S is by far the most common version of this engine and was used on most reel type mowers during the 50's. The engine can be found with both recoil start and rope start mechanisms and I have seen one with a lever starter.
