How Can I Find the Engine Serial / Model Number, Type & Trim?
The Model, Type and Code numbers, stamped directly into the engine, are used to identify our engines. Engines used in lawn mower applications usually have the model numbers stamped directly into the blower housing, muffler heat shield, or a few inches above the spark plug. Depending on the style of engine shroud used, the engine code numbers may be covered. It may be necessary to remove this shroud in order to locate the Model, Type, and Code for engine identification.

Many horizontal shaft, overhead valve engines have the serial and model numbers stamped into the OHV rocker cover. However, on certain overhead valve powered generators, the equipment manufacturer installs a decorative chrome rocker cover OVER our cover. If your engine has a decorative cover, it may be necessary to remove it in order to locate the model number, type, and engine code.

Also, be aware that the numbers found on the Engine Emissions Label (bottom left) can be confused with the engine Model, Type and Code. Unfortunately, these numbers cannot be used to identify your engine.
