GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be
sure it’s octane rating is at least as high as that recommended by
Honda. There are two types of ‘‘gasohol’’: one containing ethanol,
and the other containing methanol. Do not use gasohol that
contains more than 10% ethanol. Do not use gasoline containing
methanol (methyl or wood alcohol) that does not also contain
cosolvents and corrosion inhibitors for methanol. Never use
gasoline containing more than 5%...

High altitude operation
Operation of the engine at an altitude lower than the carburetor is
jetted for may result in reduced performance, overheating, and
serious engine damage caused by an excessively lean air/fuel
mixture. At high altitude, the standard carburetor air-fuel mixture will be ex-
cessively rich. Performance will decrease, and fuel consumption
will increase.
Even with suitable carburetor jetting, engine horsepower will
decrease approximately 3.5% for each 305 m (1,000 feet) increase
in...

Used motor oil may cause skin cancer if repeatedly left in contact
with the skin for prolonged periods. Although this is unlikely
unless you handle used oil on a daily basis, it is still advisable to
thoroughly wash your hands with soap and water as soon as
