I have an FSC pover boost valve (fuel regulator) on my 1995 STI RA and the nut on the adjustment screw has vibrated loose and the screw has turned. Problem is i dont know where it was set to before it became loose. Is there any chance anyone with an FSC regulator could have a look on theirs (under the dome headed cap nut) and tell me where the grove is facing ie. from the 12 o'clock position straight vertically down to the 6 o'clock position. It would be really apreciated as i need to drive the car later this afternoon and at the moment it definately isn't running right.

Thanks so much for you help,

Chris
