Instead of using a spline path, try using the Extrude (Multiply) tool.
With it you can set the End angle to how many turns your spiral
is to make (times 360), the number of segments in the entire
object (try turns times 32), an Offset on presumably the Y axis
that will drop the cross section down the spiral's major axis as
it turns, and an X and/or Z Offset to taper the turns if needed (I
think).
