Carburetor 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.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 335 m (1,100 ft.) above sea level
(ASL) (96.0 kPa). To maintain proper engine operation and emission
compliance above 335 m (1,100 ft.) ASL the carburetor may need to be
adjusted by an authorized service dealer.
