Carburetor Adjustment

Level 2
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.
Parts None
Required:
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.
1. Check idle speed and reset if necessary. If a tachometer is
available, idle speed screw (A) should be set to the
specifications found on "Specifications" page of this manual.
Turn idle screw (A) clockwise to increase idle speed;
counterclockwise to decrease idle speed.
When carburetor adjustment is completed, the cutting
attachment should not move at idle, otherwise serious
personal injury may result.
