If the engine is not going to be used for an extended period of
time, certain measures must be taken to protect engine against
heat, direct sun light, corrosion and formation of residues and
ingress of contaminants.
In particular the water bonded by the alcohol in the fuel causes
increased corrosion problems at engine stops or storage. Espe-
cially affected are essential engine components such as crank-
shaft bearings and conrod bearings as well as crank pins and
piston pins.
• Activate choke for a moment before stopping engine
This will draw a richer fuel/air mixture along with additional lu-
brication into the engine. This additional lubrication will aid in
protecting internal engine components from corrosion.
• Close all engine openings like exhaust pipe, carburetor and
fuel tank vents, venting tube and air filter to prevent entry of
contamination and humidity.
• Let the engine run at increased idle speed
• Shut engine down and secure against inadvertent engine
start
• Remove air filters and inject approx. 3 cm³ of preservation oil
or equivalent oil into the air intake of each carburetor
• Restart engine and run at increased idle speed for 10 - 15
seconds
• Shut engine down and secure against inadvertent engine
start
• Close all engine openings such as exhaust pipe, carburetor
and fuel tank vents, venting tube and air filter to prevent entry
of contamination and humidity.
• Let the engine run at increased idle speed
• Remove air filters and inject approx. 6 cm³ of preservation oil
or equivalent oil into the air intake of each carburetor
• Stop engine and secure against inadvertent engine start
