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 adjustment is not required for proper operation of this
engine.

Tools required: Screwdriver, Tachometer (ECHO P/N 99051130017).
Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with emissions regulations. This carburetor does not have
acceleration and high speed adjustment needles.
1. Before adjusting the carburetor, clean or replace the air filter and
spark arrestor screen.
2. Start engine and run for several minutes to reach operating
temperature.
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

clockwise to increase idle speed; counter clockwise to decrease idle
speed.
