MAINTENANCE PROCEDURE NOTES:
* Replacement is recommended based on the finding of damage or wear
during inspection.
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 1,100 feet above sea level (ASL) (96.0 kPa). To
maintain proper engine operation above 1,100 feet ASL the carburetor
might
need to be adjusted by an authorized service dealer.
If the engine is adjusted for operation above 1,100 feet ASL, the
carburetor must be re-adjusted when operating the engine below
1,100 feet ASL, otherwise severe engine damage can result.
