Kostas, when you use too large of a prop the airflow velocity through the carb is too slow reducing fuel draw. Also, where is the airbleed screw set, it should be about halfway across the inlet hole or slighly more closed.
Hobbsy,
thank you for your suggestion,
but mY English didn't help me understand what exactly you meant....[

Today ,
i checked that the correct line goes to the correct place,
and the tank's position cann't change because there isn't any space inside the fuse to move it,lower it or place it higher.
I believe that it's in the correct orrientation with the carb center line!
