Every time I've had an issue with a Rochester B it was something to do with the float. I've found that even the old brass ones are full of pinholes. The B has a split float and if the two chambers don't have exactly the same bouyancy it causes friction on the pivot point and tends to cause trouble with the fuel level in the bowl. I replaced the float with a new one a few years ago and chamfered the needle valve seat with a ball bearing and I haven't had a single leak or problem since.
