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 mean sea level

(MSL) (96.0 kPa and below). To maintain proper engine operation and

emission compliance above 1,100 feet MSL the carburetor may need to

be adjusted by an authorized ECHO service dealer.

IMPORTANT

If the engine is adjusted for operation

above

1,100 feet MSL, the

carburetor must be re-adjusted when operating the engine

below

1,100 feet MSL, otherwise severe engine damage can result.

Level 2.

Tools required:

Screwdriver, tachometer (Echo P/N 99051130017)

Parts required:

None.

NOTE

Do not adjust carburetor unless necessary. If you have difficulty,

see your ECHO dealer.

Before Adjustment

Check that:

• Air filter 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 specifications

found on Page 28 "Specifications" of this manual. Turn idle

screw (A) clockwise to increase idle speed; counter clockwise to

decrease idle speed.

4. Use a tachometer to adjust idle speed to specifications found on

page 28.
