NEEDLE VALVE INSPECTION
If foreign matter is caught between the valve seat and the
needle, the gasoline will continue flowing and cause it to
overflow.
Clean the float chamber and float parts with gasoline, if the
needle is worn as shown in the illustration, replace it together
with a valve seat. Clean the fuel passage of the mixing
chamber with compressed air.
REMOUTING AND REASSEMBLY

disassembling steps.
When installing the floating chamber, make sure to fit the
seal ring correctly.
Replace the O-ring with a new one when installing the
