Make sure the float dosen't have a crack or pinhole in it and if it's plastic it may be soaking up fuel and becoming heavier. This will cause flooding also.

Hold down GENTLY on the needle side and push down on the float. Careful or it'll fold up. You have to make sure that the float is not rubbing up against the side of the bowl too, or it will bind and keep flooding. They may well be your problem to begin with, especially if it has been tossed around some in storage. Or you could have a piece of trash under your needle.

Oh, and one more thing, make sure your float is clipped to the back of the float arm, if it isn't, that'll cause it to flood too. But that is probably not your problem since you bought it remanufactured (I would hope not anyway).
