New engines must be operated a minimum duration of two tanks of fuel 

break-in before carburetor adjustments can be made. During the break-

in period your engine performance will increase and exhaust emissions 

will stabilize. Idle speed can be adjusted as required.

This engine has been factory adjusted to maintain satisfactory starting, 

emission, and durability performance up to 1,100 feet above sea level 

(ASL) (96.0 kPa). To maintain proper engine operation and emission 

compliance above 1,100 feet ASL the carburetor may need to be ad-

justed by an authorized ECHO service dealer.

If the engine is adjusted for operation above 1,100 feet ASL, the 

carburetor must be re-adjusted when operating the engine below 

1,100 feet ASL, otherwise severe engine damage may result
