Woohoo got it fixed!
It was the mini spring (yellow arrow) that was off. It was kinda broken so it couldnt grip making it jumping off the surface its gripping.
Its good I have a spare MX to take parts from making it look like a true Black MX.
And for people wanting to do this:
Dont make the mistakes I did:
Dont take off the rewinding pole and close the back.
The mini spring is not just very hard to see, it gets tension very easy and tend to jump off alot making me lose it on the ground a few times. if you lose it use a magnet to find it.
And at last. Thanks for all the help!
