GENERAL INFORMATION
BRIGGS & STRATTON NUMERICAL MODEL NUMBER SYSTEM
This handy 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 CUBIC INCH DISPLACEMENT.
B The first digit after the displacement indicates BASIC DESIGN SERIES, elating
to cylinder construction, ignition, general configuration, etc.
C. The
second
digit
after
the
displacement
indicates
POSITION
OF
CRANKSHAFT AND TYPE OF CARBURETOR.
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
