Sounds like the hook is the right size, generally spooks use a #2 treble so anything smaller would be fine, bigger not so good. What size line are you using and how do you tie on - direct or with a snap or split ring? Line that's too thin will bring the nose down and heavy snaps and split rings will do the same.
On the cast, let the lure hang down about 12" and in one fluid motion bring the lure back and cast forward. The lure should vortex out without tumbling over causing the front hook to grab the line.
Hope that helps.
Good luck.
