RCU Forums - YS .63 Setup problem

Hi all, I have bought a YS 63 new attracted by his good performances, unfortunately during the break-in I have had to get off it the regulator adjusting screw, because the fuel didn't flow to the carburetor, resolved the problem, I have not remembered to how many turns to close again the regulator adjusting screw and the I have approximately closed. I have made the break-in and the engine it run OK up to the 60% of the power, but when I go to to the 100% of the power it lowers of turns and go off. You can suggest me to how many turns the must normally be planned the:

- Regulator adjusting screw
- High speed needle valve
- Low speed needle
