zs125-30 problems

[excrucio]

So, I have problems with my zongshen 125-30

When it is cold it starts without problems but when it is hot it is really hard to start it. If I turn carburetor so it is working with small numbers of rpm when idling it is little harder to srat if it is cold but it is easier to start it when hot.

Despite that, bike is running well when started and  except that I do not have any problems with it.

So, could someone help me?

I was able to make use of the knowledge gained there from here.
