Jumping anim montage help

So im doing a sonic project am a bit of a noob but not a total one.
I have a jumpmontage and I made a default slot from my locomotion to my final animation pose.
The in the event graph of my character i connected the input axis event JUMP to the function already jump to play anim montage.
The issue i am facing is that he jumps and then goes into a tpose.
I want to A increase the duration of the spin Jump and let him land accordingly and reset.
Any help would be appreciated.
