you can try....
With curve equation For cartesian coordinate system
r1=80 /*large radius
r2=40 /*small radius
h=100/* height of the spring
a=10 /* number or colis
x=r1*sin(t*360*a)
y=r2*cos(t*360*a)
z=t*h

you need eye to eye distance and camber length to make an ellipse of major axis and minor axis.
