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.
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.
Parts Required: None
