Thanks guys. I sold it yesterday to a Night Stalker (160th SOAR) stationed at Ft. Bragg. I hope he and his son have many happy years with it. I've had it since 1988.
Socaljoe, I didn't like the 200-4r so much but I'm fairly sure due to the symptoms that the valve body was worn out. (it acted like the TV cable was slack, or occasionally too tight.) I've read many good luck stories with it.
I had a great time here in the past and on other forums, and wouldn't trade it for the world. All of my extra parts go to the buyer if he wants them. If he does not collect them all within the next few months or so I'll be back someday selling or giving away OHC6 stuff.
