Bought fiber gasket material from NAPA (1/64") that was suitable for oil and cut out a new gasket to go between the ram cylinder and lift cover. Made 2 matching washers for the opposite side of the casting. Removed ad hoc springs that I had added to the back-pressure valve. When I tried it out, it seemed to work and DID NOT DRIFT UP. Hooked up the mower and monitored pressure while lifting slowly. Everything worked fine but I was somewhat afraid to break it so I didn't beat on it. Then I called back a potential buyer who came a few hours later. Then I went back to packing a moving truck. Later on, I sold the tractor, 2-bottom plow, 5' disc, blade, 3-row cultivator, and bush hog for 3,700 $. I think it was a pretty good deal for him and I've never been so happy to have completed a sale. The people who bought our house had a walk-through scheduled 30 min after I sold the tractor. So I'm out of the tractor business for a while. Probably will get another when we get settled in NC. So long and thanks for all the advice.
