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 Adjustment

This engine has been factory adjusted to maintain satisfactory start- ing, emission, and durability performance up to 1,000 feet above mean sea level (MSL). To maintain proper engine operation above 1,000 feet MSL the carburetor must be adjusted by an authorized Shindaiwa service dealer.

If the engine is adjusted for operation above 1,000 feet MSL, the carburetor must be re-adjusted when operating the engine below 1,000 feet MSL, otherwise severe engine damage can result.
