6.Inspect the cylinder exhaust port for any carbon buildup.

7.Gently tap the muffler on a wood surface to dislodge any loose carbon.

8.Reassemble the spark arrester, muf- fler and engine cover in the reverse order of disassembly.

IMPORTANT!

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.
