Well lets be truthful here. The valves were not "way out of adjustment". This implies that who ever installed them is an idiot who does not bother to look at his work. These valves are out of adjustment, not enough to notice with the naked eye (I am talking about the actual valve now, not the jerkyness). I know how much they are out of adjustment because I have adjusted one of them. Can anyone else say that? Not trying to be an a** here, but I make my living with these tractors, and I do not care if people speak the truth, but don't "skew" it too much. They have a problem with the valve adjustment that can be fixed. Simple enough.
