Its a number 11 o-ring. I didn't replace it because it was a new oriface. While trying to figure the whole thing, the original must have gotten changed out. The o-ring needed is more stiff than a normal o-ring. So putting a softer o-ring on the oriface was causing the creep. Changed it out, and it locks right up.O-ring around orifice? Not sure how that looks like.
Anyway, how come manual doesn't state changing that o-ring?
