cold engine vs hot engine launch

[lon]

When our engine is cold it launches like it should no bog or lag but after it warms up, it has a hard time taking off until it reaches about 10ft. Any ideas. Its a 70 cvt.
Thanks,

TORQUE SPRING Would be my first part to change.

Thanks nasty, I just changed the torque spring and that seems to have fixed it.
