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.

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, oth-

erwise severe

engine damage may result.
