Derbi Senda kickstarter problem

Hello,

I have ran into a pretty weird problem.
I was kickstarting my Derbi Senda, and the kickstarter suddenly didn't jump back.
So the first thing I did is took it apart... Oh look! The round spring that goes around the kickstarter mechanism (not the one that does all the going back work) had popped out of it's place.
So I put it back together and and tried kickstarting.



As you can see, it no longer engages the transmission immediately and doesn't jump back all the way. I really have no idea what this problem could be. I took it apart the 2nd time and same problem. When the bike is layed on the side, it jumps back perectly. Is something bent? Is something broken?

Edit: The thing tas popped out is called Kickstart Gear spring.

 

That used to happen on my speedfight. I used loads of lubricant and after a while it was ok but sometimes I'd have to force it back to correct position. You might need a new spring.
