Also try this:  Make sure fuel is delivered to the carbs under pressure (i.e.
run the car for a few seconds or work the little priming lever of the fuel 
pump),
carefully remove the piston chamber, the piston, the needle, and the spring,
and look straight down into the jet.  You should be able to see the fuel
level in the jet, about 1/4" down from top surface of the jet.
(A flashlight helps!).   If the fuel is overflowing out of the
jet, you obviously have a problem with the float or needle valve.
