Furthermore, the evaporated (gasified) gasoline is highly explosive. Work in a well-ventilated areas.

Exhaust gas contains poisonous substance. Do not keep engine running for a long period of time in a closed, or poorly
ventilated area.

Pay particular attention to the position of O-ring. Replace with new ones when disassembled.

Gasoline left in the float chamber will be deteriorated causing the slow jet to be clogged with deposits, and idling may
