You need the engine's STAMPED model, type, and code numbers, which is what the class action suit is referring to as the engine ID. Please make sure you have it in the following format: xxxxxx-xxxx-xx xxxxxxxx (model-type-trim code)
All of our engines have these numbers STAMPED, primarily by the Spark plug, muffler heat shield, rewind/blower housing or on the OHV cover (if equipped). Although some of our engines may also have a UPC barcode label, it's always best to use the STAMPED numbers as your primary source.
Keep in mind that the numbers that begin with the statement "Family:xxxxxxxx" are not the engine numbers, but rather come from the federal emissions label. You need to look for a series of STAMPED engine numbers.
