STORAGE
Gasoline engines stored over 30 days need to be
protected or drained of fuel to prevent gum from
forming in fuel system or on essential carburetor parts.
For gasoline engine protection, we recommend use of
Briggs & Stratton Fuel Stabilizer available from an
Authorized Briggs & Stratton Service Dealer. Mix
stabilizer with fuel in fuel tank or storage container. Run
engine for a short time to circulate stabilizer through
carburetor. Engine and fuel can be stored up to 24
months.
Note: If stabilizer is not used or if engine is operating on
gasoline containing alcohol, e.g. gasohol, remove all fuel
from tank and run engine until it stops from lack of fuel.
Storage Procedures for Gas/LPG/NG engines.
Fig. 2 Fig. 7
1. Change oil. See Oil service.
2. Remove spark plug and pour about 15 ml (1/2
oz.) of engine oil into cylinder. Replace spark plug
and crank slowly to distribute oil.
3. Clean chaff and debris from cylinder and cylinder
head fins, under finger guard and behind muffler.
4. Store in a clean and dry area, but NOT near a
stove, furnace or water heater which uses a pilot
light or any device that can create a spark.
