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.

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.

Parts Required:
