FUEL SYSTEM PARTS SUCH AS CARBURETOR,
FUEL FILTER, FUEL HOSE, OR TANK DURING
STORAGE. ALSO, EXPERIENCE INDICATES THAT
ALCOHOL BLENDED FUELS (CALLED GASOHOL
OR USING ETHANOL OR METHANOL) CAN
ATTRACT MOISTURE WHICH LEADS TO SEPARA-
TION AND FORMATION OF ACIDS DURING STOR-
AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYS-
TEM OF AN ENGINE WHILE IN STORAGE.
• Drain the fuel tank.
• Start the engine and let it run until the fuel lines and
carburetor are empty.
