Carburetor Adjustment

Engine Break-In
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.
High Altitude Operation
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 adjusted 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.
Level 2.
Parts Required: None
Note: Every unit is run at the factory and the carburetor is set in compliance with emission regulations.
Carburetor adjustments, other than idle speed, must be performed by an authorized ECHO dealer.
Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrestor screen is free of carbon.
• Blower pipes are installed.
