Chris 55 to 60 psi at 6200 seems a little low to me..............I wou= ld think 70 to 80 psi
would be closer to normal...........Did you by any chance replace your= oil with some
of a lower viscosity after your regulator =3Brepair ?...........Wh= at was your psi at 6200
before the regulator worked loose ?..............
