What is the amount of throw you have at high rate on the elevator up and down?

I looked online for the manual but could not find it.

I still stand by my suggestion; the Kougar is a low wing airplane so it is less neutral inverted than a midwing (like an extra) airplane would be. Thus moving the center of gravity (more appropriately the center of balance) towards the rear will help to neutralize it in an inverted position (that's how you measure the CG anyway right?). Move it back about a half inch at a time and be sure to use low rates because as I stated before as you move the CG back the elevator will become more effective. Again; the Kougar is a very stable model and should have no bad snap tendencies (I've had two and am planning my third).

Good luck and post pictures. =-)

What engine do you have in it?
