Bike won't start?

[Tukt]

Hey Here in Sweden there's currently winter and snow, when I've decided to go out riding it's been about -5 degrees celsius and it's so damn hard to fire her up for some reason.

It all started last week when I was trying to fire her up, me and dad tried kickstarting it and trying to roll it down a hill but there was no sign of life. Spark seemed to be good, even tried switching it out but didn't make things better. It got fuel running in to the engine. Anyways, I thought maybe the carb was causing it all so I teared it down and cleaned it. I wanted to do it anyways because it was overflowing all the time because of the float needle (I think?).

Anyways, mounted the carb after cleaning it, started up after a few kicks out in the cold so I had her running for a bit then thought the problem was fixed. But the next day, you had to kick like 50 times or something before she starts out of nowhere!

You kick it and kick it but doesnt show a sign of it trying to start, but then out of nowhere it just starts? Why is this?
When it's fired up and running you can turn it off and start it again with one or two kicks. It's idling and running good.

Is it some sort of adjustment on the carburetor that needs to be adjusted because of the colder air? I would like some help, my bike is a EC125 from 2010!
