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. If the seat and needle are worn beyond the permissi­
ble limits, similar trouble will occur. Conversely, if the needle
sticks, the gasoline will not flow into the float chamber. 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.
FLOAT HEIGHT ADJUSTMENT
To check the float height, invert the carburetor body, with the
float arm kept free, measure the height
®
while float arm is
just in contact with needle valve by using calipers.
Bend the tongue
