Thank you, I look at it tommorrow a little closer, if I take the vaccum out, would that mean that the waste gate would be all close, or all open?
A wee confuse on this.
How about changing the spring on the valve for a stronger one, to delay the opening ( this if the gate is opening to let the pressure out), or the oposite , a stronger spring if the gate need to be shut for longer?
Thank you.
Olivier
