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.

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.

Parts Required: None
