If gas is not cut off from valve it will dribble all hole until pressure dies down from gas pump. Additonally, check your oil for gas. If this dribbling goes on after car off, there may be gas in oil. Improper cutoff from float can lead to gas not being atomized or too rich keeping car from running.
