note!
It is very important to set the throttle in the correct position before attempting to start the engine. It is

When the engine emits more fuel or thick smoke or accelerates slowly, it indicates that the engine is too rich in fuel. Please rotate the main oil needle
clockwise, in units of 15°, and gradually reduce the main oil needle until the engine exhaust sound is soft and powerful. Slight smoke and lubricating fuel
spew from the exhaust pipe.
