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 1,100 ft. (335 m) above sea
level. To maintain proper engine operation and emission compliance above
1,100 ft. (335 m) ASL the carburetor may need to be adjusted by an
authorized service dealer.
If the engine is adjusted for operation above 1,100 feet (335 m)
above sea level, the carburetor must be re-adjusted when operating
the engine below 1,100 ft. (335 m) above sea level, otherwise severe
engine damage may result.
