well it worked bad at first atempts because i was trying to find the seting to start by working from "open to close", this afternoon i changed my mind and made my first atempts to sart with 1/4 , and after 1/2 turn.

Hey Dave !!! we are overseas here, no toll free numbers to call with my bad needle. Will have to go to a LHS, compare my needle with a normal .15 one and then order one. The engine is new but it's a second hand purchase, so no way to obtain a free needle.

I'll go like that for first engines flights and if engine behaviours are correct it will stay like that
