Carburetor Adjustment
The blades must not move at idle, otherwise serious personal
injury may result. Periodic carburetor adjustment may be
necessary to assure blades do not move at idle. If blades move,
readjust carburetor according to these instructions, or see your
ECHO Dealer.
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.
