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.
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 difficultly,
see your ECHO dealer.
