SECTION 1 GENERAL INFORMATION

BRIGGS & STRATTON NUMERICAL IDENTIFICATION SYSTEM
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.
