Hola Gianni, long time no talk.....LOL.........well I've seen your other thread but I'm not goin to say anything except it's too lean....I HAVE had this happen to me before....just go and richen it up a little (you know how to do that right?? (turn HS needle clockwise a few click))......start then engine up, and see it the engine bogs down or anything.....if it takes a while for the engine to get up to speed up, then it is too rich, so oddly engough, you need to lean it out a few clicks...

Hope this helps.....
