This engine will have proper engine performance and emission control
when it is operated at or below an altitude of 5000 feet (1524 meters).
This engine requires a high altitude carburetor kit to ensure proper
engine performance and emission control when it is operated at
altitudes above 5000 feet (1524 meters). Operating the engine with
the wrong engine configuration above 5000 feet (1524 meters) may
increase its emissions and decrease fuel efficiency and performance.
To obtain a high altitude carburetor kit, contact FNA Group at
cservice@fna-group.com or 1-877-362-4271.
