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
feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 1,100 feet ASL
the carburetor may need to be adjusted by an authorized Shindaiwa service dealer.
NOTE:
Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor adjust-
ments, other than idle speed, must be performed by an
authorized Shindaiwa dealer.
IMPORTANT!
If the engine is adjusted for operation above 1,100 feet
ASL, the carburetor must be re-adjusted when operat-
ing the engine below 1,100 feet ASL, otherwise severe
engine damage may result.
