Also make sure choke is opening all the way.

Serge,
   this thread and your other carb thread are very similar, so I think you should keep all the Information in one thread.   It will help those trying to help you, so that they understand the whole scope of the issue you are having.    
That said, the floats are inside the fuel bowl of the carburetor.   you need to bend the tab on the float so that the needle and seat shuts off the incoming fuel at a certain float level.    I would recommend that you have someone familiar with carburetors help you at this point. While I don't doubt your ability to tear down and re-assemble, you have missed some critical steps in the carb rebuild process....   you need someone to help you understand the instructions and get this correct.    it sounds like you may be on the fast track to an engine fire, or filling your oil sump with gasoline..
