Carburetor Adjustment
Every unit is run at the factory and the carburetor is set in compliance with
emission regulations. In addition, the carburetor is equipped with “ H ” (High
Speed) and “ L ” (Low Speed) needle adjustment limiters that prevent
settings outside acceptable limits.
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 335 m (1,100 ft.) above sea level (ASL)
(96.0 kPa). To maintain proper engine operation above 335 m (1,100 ft.)
ASL the carburetor might need to be adjusted by an authorized service
dealer.
If the engine is adjusted for operation above 335 m (1,100 ft.) ASL,
the carburetor must be readjusted when operating the engine below
335 m (1,100 ft.) ASL, otherwise severe engine damage can result.
