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) is permitted.
Do not use unapproved gasoline, such as E15 and E85. Do not mix oil in gasoline or change the engine to operate on alternate fuels. Use of unapproved fuels could result in damage to engine components, which will not be repaired under the warranty.
To protect the fuel system from gum formation, and corrosion, mix an alcohol-free fuel stabilizer and ethanol treatment into the fuel. Refer to the
Storage
 section. All fuel is not the same. If start or performance problems occur, change fuel providers or brands. This engine is certified to operate on gasoline. The emissions control system for carbureted engines is EM (Engine Modifications). The emissions control systems for engines with electronic fuel injection are ECM (Engine Control Module), MFI (Multiport Fuel Injection), TBI (Throttle Body Fuel Injection) and if equipped an O2S (Oxygen Sensor).

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON) gasoline is permitted.
For carbureted engines, high altitude adjustment is required to maintain performance. 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, no high altitude adjustment is necessary.

Maintenance Information

Fuel and its vapors are flammable and explosive. Fire or explosion could result in burns or death.
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted in a different direction, it will not easily start because of oil or fuel contamination of the air filter or the spark plug.
Accidental engine spark can cause an electric shock, fire or explosion and could result in entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
  • Disconnect all spark plug wires and keep them away from the spark plugs.
  • Disconnect the battery wire from the negative battery terminal (only engines with electric start).
  • Use only the correct tools.
When you check for spark:
  • Use an approved spark plug tester.
  • Do not check for spark with the spark plug removed.
All the components used to assemble this engine must stay in the initial position for correct operation. Damage or injury can occur if you use incorrect parts or you do not replace all parts on the engine.
  • Replacement parts must be of the same design and installed in the same position as initial parts.
  • If installed, do not change the governor spring, links, or other parts to increase the engine speed.

Fuel System

Fuel System-Mow-Stow
Fuel and its vapors are flammable and explosive. Fire or explosion could result in burns or death.
Fuel Storage
  • Because pilot lights or other ignition sources can cause explosions, keep fuel or equipment away from furnaces, stoves, water heaters or other appliances that have pilot lights.
Some models have a fuel tank for vertical storage that will let the engine tilt for maintenance or storage (C, Figure Figure 1). Do not keep in vertical position with the fuel tank filled above the bottom of the fuel level indicator (D), if equipped. For more instructions, refer to the equipment manual.
Keep the engine level (normal operating position). Fill the fuel tank (A, Figure Figure 1) with fuel. For fuel expansion, do fill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. The use of an alcohol-free fuel stabilizer and ethanol treatment in the fuel storage container is recommended. This keeps fuel fresh and decreases fuel-related problems or contamination in the fuel system.
When you fill the fuel container with fuel, add an alcohol-free fuel stabilizer to the specified instructions by the manufacturer. If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Operate the engine until it is out of fuel.

Power Ratings

With title displayed. Power ratings disclaimer statement approved on 3/1/2013. For Briggs & Stratton engine equipped models use *. ***Revision A, no changes. Only revised to allow translator to proof-read original text. 
The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given the wide array of products on which engines are placed, the gasoline engine may not develop the rated gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this engine.

Look For Relevant Emissions Durability Period and Air Index Information On Your Small Off-Road Engine Emissions Label

Engines that are certified to meet the California Air Resources Board (CARB) small off-road Emissions Standard must display information regarding the Emissions Durability Period and the Air Index. Briggs & Stratton makes this information available to the consumer on our emissions labels. The engine emissions label will indicate certification information.
The
Emissions Durability Period
 describes the number of hours of actual running time for which the engine is certified to be emissions compliant, assuming proper maintenance in accordance with the Operator’s Manual. The following categories are used:
Moderate:
Engines at or less than 80 cc displacement are certified to be emissions compliant for 50 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions compliant for 125 hours of actual engine running time.
Intermediate:
Engines at or less than 80 cc displacement are certified to be emissions compliant for 125 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions compliant for 250 hours of actual engine running time. 
Extended:
Engines at or less than 80 cc displacement are certified to be emissions compliant for 300 hours of actual engine running time. Engines greater than 80 cc displacement are certified to be emissions compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year. Therefore, the
Emissions Durability Period
 of an engine with an
intermediate
 rating would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emissions requirements.
For engines at or less than 80 cc displacement:
Category C = 50 hours, Category B = 125 hours, Category A = 300 hours
For engines greater than 80 cc displacement and less than 225 cc displacement:
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
For engines of 225 cc or more displacement:
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
