Watch the basic concept of 4 cycle theory at work with state of the art graphics produced by the Briggs & Stratton Customer Education Department. First, we identify and highlight the similarities and differences between the two types of engines (single cylinder and v-twin) currently produced by Briggs & Stratton. Topics include crankshaft orientation, application usage and many more.

Then watch and learn about basic engine operation and how the proper air, gas, spark and compression combination rotates the crankshaft.

Finally, we cover 4 stroke engine theory using an overhead valve engine as the model. We discuss and demonstrate in graphical detail the inner workings of the engine and how the 4 strokes (intake, compression, power, and exhaust) combine to produce power. Which in turn, makes it easier for you to get stuff done.
