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.
Before Adjustment

• Air lter is clean and properly installed.
• Spark arrestor screen is free of carbon.
• Blower pipes are installed.
1. Start engine, run at idle for one minute.
2. Complete warm up by running at full throttle for 5 minutes, oper-
ating choke twice to clear air from carburetor chambers.
3. Check idle speed and reset if necessary. If a tachometer is avail-
able, idle speed screw (A) should be set to the specications

crease idle speed.
