Start The Engine - Briggs & Stratton 2691485-00 Manual Del Operario

• At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane / 85 AKI (89 RON) gasoline is acceptable.
• For carbureted engines, high altitude adjustment is
required to remain emissions compliant. Operation
without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. Contact a Briggs & Stratton Authorized
Service Dealer for high altitude adjustment information.
• Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not
recommended.
• For Electronic Fuel Injection (EFI) engines, high altitude
adjustment is not necessary.
