    I found that I had e leaking needle valve, my engine was flooded in gasoline.

    Since I had nothing to loose i tried the following method do solve this issue:

    Got some valve lapping compound (very thin), put a tiny drop at the tip of the needle, and some WD40 or similar to make it a little thinner. Gently and carefully i made the circular motions like I was actually lapping a valve.

    After a few tentatives the leaking problem is finally solved. How I know it is?

    Simple: Got some "crystal" transparent hose and a syringe, (my engine is over the working table now), filled the bowl with fuel, and let an excess rise at the hose I previously attached to the carb, then I marked the level at the hose and let the whole thing quiet over night.
