Carter AFB Fuel Leakage

I recently rebuilt a Carter AFB (9637S) for use in my '71 Mercury with a 400. I was having problems starting the car after it sat overnight. After it was warmed up it started fine. Upon removing the carb I noticed that it was leaking fuel into the intake from under the carb. When I opened it up I noticed the float bowls had abouit a 1/4 inch of fuel left in them. I checked the float level and they seem to be in spec. Any suggestions as to what may be causing this? Thanks.

Most carbs with main well plugs due to the use of metering rods do this, Quadrajets are notorious for it. As for a carter I never heard of them doing it, but I`m not real familiar with them.
Anyways, you`ll have to remove the carb and check the plugs, on Q-jets they can be restaked with a punch and hammer, then coated with a fuel proof epoxy, if your carter is the same way you can do the same thing.
