from operation. See Change Oil in Section 6.

or the gasoline must be treated with a stabilizer
to prevent deterioration. If you choose to
use a stabilizer, follow the manufacturer’s
recommendations, and add the correct amount
for the capacity of the fuel system.
Fill the fuel tank with clean, fresh gasoline. Run
the engine for 2 to 3 minutes to get stabilized fuel
into the carburetor.
