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 adjustments,

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 operating the

engine below 1,100 feet ASL, otherwise severe engine damage may result.
