NEEDLE VALVE
If foreign matter is caught between the valve seat and the nee-
dle valve, the gasoline will continue flowing and overflow. If the
valve seat and needle valve are worn beyond the permissible
limits, similar trouble will occur. Conversely, if the needle valve
sticks, the gasoline will not flow into the float chamber. Clean the
float chamber and float parts with gasoline. If the needle valve is
worn, as shown in the illustration, replace it along with a new
valve seat. Clean the fuel passage of the mixing chamber using
compressed air.
