TECHNICAL & CONSUMER INFORMATION
Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture wil! be too rich. Performance wil!
decrease , and fuel consumption w i l! i ncrease. A very rich mixture wil! also foul the spark
plug and cause hard starting. Operation at an altitude that differs from that at which this
engine was certified, for extended periods of time , may increase emissions.
High altitude performance can be improved by specific modifications to the carburetor. If
you always operate your engine at altitudes above 5,000 feet (1,500 meters) , have your
servicing dealer perform this carburetor modification. This engine, when operated at high
altitude with the carburetor modifications for high alt i tude use, wil! meet each emission
standard throughout its useful life.
Even with carburetor modification , engine horsepower will decrease about 3.5% for each
1 , 000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be
greater than this if no carburetor modification is made.
NOTICE
When the carburetor has been modified for high altitude operation , the air-fuel mixture
wil! be too lean for low altitude use. Operation at altitudes below 5,000 feet (1 , 500meters)
with a modified carburetor may cause the engine to overheat and result in serious engine
damage. For use at low altitudes , have your servicing dealer return the carburetor to
original factory specifications .
Oxygenated Fuels
Some conventional gasolines are being blended with alcohol or an ether compound .
These gasolines are col!ectively referred to as oxygenated fuels.
To meet clean air standards , some areas use oxygenated fuels to help reduce
emissions.
If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane
rating requirement.
Before using an oxygenated fuel, try to confirm the fuel's contents. Some areas require
this information to be posted on the pump.
The following are the EPA approved percentages of oxygenates:
ETHANOL ----(ethyl or grain alcohol) 10 % by volume
You may use gasoline containing up to 10 % ethanol by volume.
Gasoline containing ethanol may be marketed under the name
"Gasohoi".
MTBE -----(methyl tertiary butyl ether) 15% by volume
You may use gasoline containing up to 15% MTSE by volume.
METHANOL ---(methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 50/0 methanol by volume,
