After spooling, take the rod to a large open space (ballfield , park, whatever)
With the line through all of the guides as normal, tie it to a fence, branch, tree, etc.
Open the bail and walk with the rod until most or all of the line is out.
Now put the rod down and walk back to where it was tied and cut it.
Go back to the rod, close the bail, pinch the line with one hand and reel in with the other.
By doing this, all of the kinks and coils will work themselves out.
