Carburetor Adjustment
Level 2.
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 and
durability performance up to 330 m (1100 ft.) above sea level (ASL)
(96.0 kPa). To maintain proper engine operation and emission compliance
above 330 m (1100 ft.) ASL the carburetor may need to be adjusted by an
authorized service dealer.
If the engine is adjusted for operation above 330 m (1100 ft.) ASL, the
carburetor must be re-adjusted when operating the engine below
330 m (1,100 ft.) ASL, otherwise severe engine damage may result.
Note: Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor
adjustments, other than idle speed, must be performed by an
authorized dealer.
