carburetor adjustment

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 ad- justed by an authorized ECHO service dealer.

Important

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.

Level 2.

Parts required: None.

NOTE

Every unit is run at the factory and the carburetor is set in compli- ance 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 avail- able, 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.
