I have just cleaned the carburetor on my 2005 Gas Gas TXT 125 pro and did not notice the "groove" in the needle valve when i took it off the carburetor.

i am pretty sure it does not matter which way the "groove" in the neddle points to but i rather ask my fellow members here at the forum. So must the "groove" in the needle valve point towards a spesific direction? 

The carburetor had quite a lot of corrosion/green stuff inside because of the needle lifter and the 2 floats. Checked the floats for any holes but the floats are the white plastic type and you can see if any fuel is inside the floats.

I did install to floats the correct way with the "tip" on each of the floats down at the bottom of the metal tank 

 

I also bought a "gasket kit" which contains of 1 large O ring where i have no idea where it goes (the O ring is to small for the metal tank and to large for the carb cover) and 2 washers for the carburetor cover. That is all that was in the bag...

That groove was for a clip that held it in place on the floats.

It does not matter where your arrowed groove is pointing to. The float arms connect to the pin extending from the valve body via a forked clip. Been a few years since I stripped a DellOrto so I could be wrong about the clip. Bye, Peter B.
