To identify an OHV Briggs & Stratton engine, locate the model number, type, and code stamped on the engine's metal plate, typically found on the engine's blower housing or cylinder block. The model number usually consists of a series of numbers and letters, while the type and code provide specific details about the engine's configuration and manufacturing date. Additionally, you can identify the engine by its overhead valve design, which features valves located above the combustion chamber, distinguishing it from other engine types.
