Common Questions
10 totalHow do I properly check and add oil to my Briggs & Stratton engine?
To check the oil level, place the engine level, remove the dipstick, wipe it clean with a cloth, replace and tighten it. Check the oil level; if needed, add oil slowly until it reaches FULL line on dipstick (do not overfill). (Page 12)
What octane of gasoline should I use in my engine?
Always use unleaded automotive gas with a minimum octane rating of 87 AKI (91 RON). If operating at high altitude, the same type of fuel can be used but an additional carburetor jet kit might be required. Do not mix oil with gasoline. (Pages 13 and 26)
How often should I perform maintenance on my Briggs & Stratton engine?
Regular maintenance is necessary to improve performance and extend the life of the engine. Check oil level daily or every 8 hours; clean debris daily or before each use; inspect spark plug every 100 hours; change oil after first 5-8 hours then every 50 hours under normal conditions, every 25 hours under heavy load/high temperatures. Replace air filter when it is very dirty. See Maintenance Schedule for full details (Pages 16-17).
What should I do if my engine floods with fuel?
If the engine floods, set the choke to open/run position and continue cranking until it starts. (Page 8)
How can I safely store my Briggs & Stratton engine for an extended period?
Before long-term storage, change oil while the engine is still warm; pour about a half-ounce of oil into spark plug cavity and crank starter rope slowly to distribute; add fuel stabilizer or drain gas from tank if not using Fresh Start™ cap; clean dirt from entire unit removing combustible materials around muffler. Store in dry conditions out of reach of appliances with open flame/pilot light (Page 19).
How do I replace the air cleaner on my engine?
To remove a flat air filter, loosen screw and tilt cover down to take out cartridge; install new clean cartridge with pre-cleaner lip at bottom of cartridge pleats. Insert tabs into slots on base and tighten screws. For oval cleaner: Loosen two screws lift off cover, replace with new cartridges then put cover back tightening the screws (Pages 17-18).

#### Stopping
WARNING
Do not stop engine by moving choke control to CHOKE. Backfire, fire or engine damage could occur.
Oil Check oil level before starting the engine. Keep oil level at FULL. Do not overfill. Check level daily, or after every eight (8) hours. Capacity
Engine oil capacity is 2/3 qt. (22 oz.; 0.65 liter). NOTE: Often residual oil remains in engine. Fill to FULL line on dipstick.
Oil Recommendation Use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. Do not use special additives. SAE 30 40 F and higher (5 C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting. 10W-30 0 to 100 F (−18 to 38 C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80°F (27°C) or higher.


Check oil level frequently at higher temperatures.
Synthetic 5W-30 −20 to 120 F (−30 to 40 C) provides the best protection at all temperatures as well as improved starting with less oil consumption.
5W-30 40 F and below (5 C and below) is recommended for winter use, and works best in cold conditions.

#### Fuel Type of gasoline to use
This engine is certified to operate on gasoline. The emission control system for this engine is EM (Engine Modifications).
Always use gasoline that meets these requirements:
All gasoline is not the same. If you experience starting or performance problems after new gasoline has been used in your engine, switch to a different fuel provider or change fuel brands.
|CAUTION| |---| |Some fuels, called oxygenated or reformulated fuels, are fuels blended with alcohols or ethers. Excessive amounts of these blends can damage the fuel system or cause performance problems. If any undesirable operating symptoms occur, use gasoline with a lower percentage of alcohol or ether.|
####### Fuel Storage
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in fuel system or on essential carburetor parts. Mix fuel stabilizer with fuel in tank or storage container. Run engine for a short time to circulate stabilizer through carburetor and engine. Engine and fuel can be stored up to 24 months.
If fuel stabilizer is not used, you need to drain gasoline from equipment prior to storage.
If the FRESH START™ continuous fuel preserver fuel cap (concentrated liquid cartridge) is used, there is no need to drain fuel, as long as cartridge contains stabilizer for seasonal storage.
####### Fuel Stabilizer
To protect the fuel system from gum formation, use Briggs & Stratton FRESH START fuel stabilizer plus, or FRESH START continuous fuel preserver fuel cap (concentrated liquid cartridge), or FRESH START preservative & stabilizer (granular).
####### High-altitude Use
At higher altitudes (over 5,000 feet), 85 octane/85 AKI (89 RON) gasoline can be used. Operation at high altitude may require a high-altitude carburetor jet kit to improve performance and decrease fuel consumption. See your local authorized Briggs & Stratton dealer for more information.

#### Technical Information
############# Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating
the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site” or net power). This difference is due to a variety of factors including, but not limited to, accessories (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 Series engine.
#### Emission Information
Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards must display information regarding the Emissions Durability Period and the Air Index. Briggs & Stratton makes this information available to the consumer on our emission labels. The engine emission 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 Operating & Maintenance Instructions. The following categories are used:
Moderate: Engine is certified to be emission compliant for 125 hours of actual engine running time.
Intermediate: Engine is certified to be emission compliant for 250 hours of actual engine running time.
Extended: Engine is certified to be emission 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.
Certain Briggs & Stratton engines will be certified to meet the United States Environmental Protection Agency (USEPA) Phase 2 emission standards. For Phase 2 certified engines, 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 emission requirements.
For engines less than 225 cc displacement. Category C = 125 hours
For engines of 225 cc or more displacement. Category C = 250 hours

ABOUT YOUR ENGINE WARRANTY
Briggs & Stratton welcomes warranty repair and apologizes to you for being inconvenienced. Any Authorized Service Dealer may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example, warranty would not apply if engine damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, warranty is void if the serial number of the engine has been removed or the engine has been altered or modified.
If a customer differs with the decision of the Service Dealer, an investigation will be made to determine whether the warranty applies. Ask the Service Dealer to submit all supporting facts to his Distributor or the Factory for review. If the Distributor or the Factory decides that the claim is justified, the customer will be fully reimbursed for those items that are defective. To avoid misunderstanding which might occur between the customer and the Dealer, listed below are some of the causes of engine failure that the warranty does not cover.
############# Normal wear:
Engines, like all mechanical devices, need periodic parts service and replacement to perform well. Warranty will not cover repair when normal use has exhausted the life of a part or an engine.
############# Improper maintenance:
The life of an engine depends upon the conditions under which it operates, and the care it receives. Some applications, such as tillers, pumps and rotary mowers, are very often used in dusty or dirty conditions, which can cause what appears to be premature wear. Such wear, when caused by dirt, dust, spark plug cleaning grit, or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty.
This warranty covers engine related defective material and/or workmanship only, and not replacement or refund of the equipment to which the engine may be mounted. Nor does the warranty extend to repairs required because of:
Warranty is available only through service dealers which have been authorized by Briggs & Stratton Corporation. your nearest Authorized Service Dealer is listed in the “Yellow Pages™” of your telephone directory under “Engines, Gasoline” or “Gasoline Engines,” “Lawn Mowers,” or similar category.
