made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed
can be adjusted as required.
BEFORE MAKING ADJUSTMENTS:
1. The correct spark plug must be clean and properly gapped.
The air filter element must be clean and properly installed.
2.
The muffler spark arrestor screen and exhaust port must be clear of carbon.
3.
4. The standard bar and chain combination (refer to the section, Technical Data) must be installed to the power head,
and properly tensioned.
