The list on the following page indicates Engine Type Numbers and corresponding Model Numbers.

If a model number of which the first three numbers are 500., it indicates a Briggs & Stratton Engine sold to Sears Roebuck & Co. The number following the 500., is the type Number. Reference to this list will enable you to identify model letters.

Example:
