Warning
Gasoline is a low ignition point and explosive materials, so always work in a well-ventilated
place and strictly prohibit flame when working with gasoline.

When disassembling fuel system parts, pay attention to O-ring position, replace with new
one as re-assembly.
There is a drain screw in the float chamber for draining residual gasoline.
