ASSEMBLY
Type of Fuel
1. Always use clean, fresh, unleaded gasoline with a
minimum of 87 octane/87 AKI (91 RON). Do Not
mix oil with fuel. Do not modify the engine fuel
system or carburetor to run on alternative fuels.
NOTE: Fuel with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether), is acceptable.
IMPORTANT: Use of any fuel other than those
approved above will void warranty. Some areas
require that fuel pumps be marked if the fuel contains
alcohols or ethers. If you are not sure if your fuel
contains alcohol or ethers that are different than those
approved above, then check with the service station
operator.
2. Clean area around fuel fill cap, remove cap.
3. Using a fuel funnel (optional), slowly add unleaded
gasoline until fuel level is approximately 1” below
top of fuel tank neck to allow for fuel expansion
(Figure 2). Be careful not to overfill.
4. Install fuel cap and let any spilled fuel evaporate
before starting engine.
To avoid engine performance issues, the fuel system
should be treated with a fuel preserver or emptied
before storage of 30 days or longer. To protect the fuel
system from gum formation, use Briggs & Stratton
FRESH START™ fuel stabilizer plus. If fuel preserver
is not used, drain the fuel tank, start the engine and let
it run until the fuel lines and carburetor are empty. Use
fresh fuel next season. See “Storage” on page 18 for
additional information.
NEVER use engine or carburetor cleaner products in
the fuel tank as permanent damage may occur.
High-altitude use
Operation at high altitude (over 5,000 feet), 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.
