Operating the engine with the wrong engine configuration at a given altitude may increase
its emissions and decrease fuel efficiency and performance. When the carburetor has
been modified for high altitude operation, the air-fuel mixture will be too lean for low
altitude use. Operation at altitudes below 609.6 meters (2,000 feet) with a modified
carburetor may cause the engine to overheat and result in serious engine damage. For
use at low altitudes, have your dealer return the carburetor to original factory
specifications.
