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.
Do not bend or twist throttle valve cable. Damaged cable will make unstable
driveability.
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.
Do not disassemble automatic by-starter and air cut-off valve arbitrarily.
