.Briggs & Stratton Animal is a single cylinder, four stroke overhead valve engine used in many go-karting series. I used a different engine during my design project of The Camel, Supermileage vehicle, which was the Briggs & Stratton Model 20. I modeled both on SolidWorks as well as other engines, but this one is my favorite. Obviously, it's not complete yet, as it lacks the Carburetor and Head Assemblies. I'll complete the model as soon as I get my hands on good reference images that I couldn't find anywhere. Below is an exploded view of the Animal engine.
