5-2 Precautions In Operation General Information 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. Cautions • Do not bend off throttle cable. Damaged throttle cable will make unstable drive-ability. • 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 air cut valve arbitrarily.
