had same thing happen on ford 8n. turned out my float had a hole in it and it was actually sinking. Did you replace needle and seat together? Older sets are a machined needle and seat and should be replaced together or you might not get a good seal. I'm leaning towards bad float though

It could also be some dirt under the needle valve keeping it from closing completely. Did you use some sealant under the seat. Sometimes they will leak from behind the seat.

Ive never put any type of sealant on a seat before, the kits I get have a small round gasket for that. Just curious what type of sealant your using there.

Sometimes the washers (gaskets) will not seal due to pitting of metal of the body. A very thin coat of sealant such as black permatex on the washer. Apply with a toothpick - it doesn't take much - and it can prevent a problem.

I have to admit that Ive never had that problem. I guess Ive been lucky so far.
