RT 125 2002 cold start problem

[berkay_0618]

Hello everyone! I have a problem with my RT 125 2002. When the bike engine gets cold it cannot start without the choke. I’ve opened the carburetor and cleaned the jets and checked the fuel air mixture and for a day it worked without the choke. I’ve opened the carburetor again and everything’s clean. The carburetor has another problem- when the bike is working it has a little leak from the carb. What i need to check or replace to fix these problems?
