CS-355T

 

 

Carburetor Adjustment

 

 

Every unit is run at the factory and the carburetor is set in

T

compliance with Emission Regulations. In addition, the

 

carburetor is equipped with “H” (High Speed) and “L” (Low

L H

Speed) needle adjustment limiters that prevent settings

outside acceptable limits.

 

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.

1.Before adjusting carburetor clean or replace air filter and muffler “Spark Arrestor Screen”.

2.Make sure the bar and chain are properly adjusted.

3.Start engine and run several minutes to bring to operating temperature. Flash choke twice during warm-up to clear any air from the fuel system.

4.Stop engine. Turn “H” speed needle counterclockwise (CCW) to stop. Turn “L” speed needle midway between full clockwise (CW) stop and CCW stop.

5.Idle Speed Adjustment:

•Start engine, turn “Idle” speed adjustment screw “T” CW until the saw chain begins to move, then turn screw out CCW until the saw chain stops moving. Turn screw out, CCW, an additional 1/4 turn.

When carburetor adjustment is completed, the saw chain should not move at idle, otherwise serious personal injury may result.

6.Accelerate to full throttle for 2 - 3 seconds to clear any excess fuel in the engine, then return to idle. Accelerate engine to full throttle to check for smooth transition from idle to high speed. If engine hesitates turn “L” needle CCW 1/8 turn and repeat acceleration. Continue adjustment until smooth acceleration results.

7.Check idle speed and reset if necessary as described in item 5. If a tachometer is available idle speed should be set to value listed on technical data page.

When starting, idling adjustment speed should be adjusted to prevent the saw chain from moving. When you experience trouble with the carburetor, contact your dealer.
