Foreword
This manual was written to assist engine technicians and service personnel with the repair and maintenance
procedures for Briggs & Stratton® engines. It assumes that persons using this manual have been properly
trained in and are familiar with the servicing procedures for these products, including the proper use of
required tools and safety equipment and the application of appropriate safety practices. Persons untrained
or unfamiliar with these procedures or products should not attempt to perform such work.
Proper maintenance and repair is important to safe, reliable operation of all engines and engine-driven
systems. The troubleshooting, testing, maintenance, and repair procedures described in this manual are
appropriate for the Briggs & Stratton engines described herein. Alternative methods or procedures may pose
risk to personal safety and the safety and/or reliability of the engine and are not endorsed or recommended
by Briggs & Stratton.
All information, illustrations, and specifications contained in this manual were based on the data available
at the time of publication. Briggs & Stratton Corporation reserves the right to change, alter, or otherwise
improve the product or the product manuals at any time without prior notice.
Briggs & Stratton offers two complementary publications to enhance understanding of engine technology,
maintenance, and repair. (Neither publication, however, is a substitution for a recognized training program
for engine technicians.)
• For consumers,
Small Engine and Equipment Maintenance Guide (p/n CE8155) provides a comprehensive
overview of how small air-cooled engines work, basic troubleshooting, and step-by-step maintenance
procedures.
• For engine technicians and consumers alike, an in-depth study of engine theory and operation can be
found in the textbook
Small Engines (p/n CE8020).
Both publications can be purchased at BRIGGSandSTRATTON.COM or through a local Briggs & Stratton
Authorized Service Dealer.
