BRIGGS & STRATTON NUMERICAL IDENTIFICATION SYSTEM
YOUR KEY TO THE WORLD'S FINEST ENGINES
This chart explains the unique Briggs & Stratton numerical model designation system. It is possible to determine most of the
important mechanical features of the engine by merely knowing the model number. Here is how it works:
A. The first one or two digits indicate the approximate CUBIC INCH DISPLACEMENT.
B. The first digit after the displacement indicates the BASIC DESIGN SERIES, relating to cylinder
construction, ignition, general configuration, etc.
C. The second digit after the displacement indicates ORIENTATION OF CRANKSHAFT.
D. The third digit after the displacement indicates TYPE OF BEARINGS, and whether or not the
engine is equipped with REDUCTION GEAR or AUXILIARY DRIVE.
E. The last digit indicates the TYPE OF STARTER.
