Re: Rebuilt Flathead Problems.
Checking spring pressure: I had a hard time coordinating drill press with the spring not at eye level and reading the scale. I made this indicator to tell me when the spring and guide were at the same height. A carriage bolt through a piece of board with a ground wire at the bottom. Cut the bolt to the length of the shortest installed height you measured. Place a nut on the threads to adjust for varying heights. Use a flat, rigid, piece of steel to press the valve. Attach an analog ohm meter to the carriage bolt ground and to the flat piece on top of the valve. Press the valve until the analog meter swings and read the scale.
sorry about the rotated pictures, they were straight on my computer.
