Operation

Fuel Recommendations

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON).
High altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
NOTICE: Do not use unapproved gasoline, such as E85.
Do not mix oil in gasoline or modify the engine to run on
alternate fuels. This will damage the engine components
and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. All fuel is not the same. If starting
or performance problems occur, change fuel providers
or change brands. This engine is certified to operate on
gasoline. The emissions control system for this engine is
EM (Engine Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane/85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See a Briggs & Stratton Authorized
Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude kit is not recommended.

Add Fuel

Fuel and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or
death.
When Adding Fuel
• Turn engine off and let engine cool at least 3 minutes before
removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel, do
not fill above the bottom of the fuel tank neck.
• Keep fuel away from sparks, open flames, pilot lights, heat,
and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks
or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the
fuel cap (A, Figure 4).
2. Fill the fuel tank with fuel. To allow for expansion of the
fuel, do not fill above the bottom of the fuel tank neck.
3. Reinstall the fuel cap.
