The Model, Type and Code numbers, stamped directly into the engine, are used to identify our engines. Engines used in lawnmower applications usually have these numbers stamped into the blower housing, muffler heat shield or a few inches above the spark plug. Depending on the type of engine shroud used, the engine numbers may be covered. It may be necessary to remove this shroud in order to locate the Model, Type, and Code.
Many horizontal shaft, overhead valve engines have these numbers stamped into the OHV rocker cover. However, on certain overhead valve powered generators, the equipment manufacturer installs a decorative NULL OVER
our cover. If your engine has a decorative cover, it may be necessary to remove it in order to locate the Model, Type, and Code.
Please visit our Identify Your Model Number page for help in finding the engine’s numbers. For an explanation of our numbering system, please visit our Numerical Designation System page. Also, be aware that the numbers found on the Engine Emissions Label can be confused with the engine Model, Type, and Code. Unfortunately, these numbers cannot be used to identify your engine.
