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; counter 
clockwise to decrease idle speed.
When carburetor adjustment is completed, the cutting 
attachment should not move at idle, otherwise serious
