Great news! Sorry it took a while to get back but life happens. Spring was definitively the issue but also found a piece of debris on the plunger that appeared to be from the previous leather sweeper ring on the shaft that had deteriorated. Replaced with new spring and reinstalled. Used 12 step bleed method with pressure pot. Flaps are now better than I’ve had them in 20 years! Thanks again for all the help. The biggest clue was this video. My spring had no springiness left. There is no way that ball was staying in place with the way the spring was before it fixed it!

Ok thanks. I took it back off once and opened it and went through it. I had thought the same thing and verified everything was still there and put back together. So the ball is probably just not seating. Solution on this? New ball? New seat? Springs? All of the above? Thank you in advance and appreciate your flap expertise from previous posts you’ve done!

Can I jump in and hijack this thread? I have been lurking for a bit. A and p here. 1965 m20e. Overhauled the pump with the oring kit from laser. I’ve verified the correct placement of springs and ball bearings etc. reinstalled. Used the 12 step plan posted on here by the flap guru. Back-bled with pressure pot. Feels like there is no pressure when trying to pump flaps down. I can pump it down if I have the speed screw adjusted all the way down. It will pump down and hold pressure so the actuator isn’t leaking. In this configuration however it will no retract. If I make a micro adjustment on the retracting speed screw then it will not stay down when pumped down (still with very little to no pressure. Infinite pumps basically). I’m thinking maybe there is an issue with this flap speed retraction adjustment screw but maybe I don’t have enough air out of the system somehow even after back bleeding? Maybe both? If I missed something in my description forgive me. Ask questions and I will try and get back quickly.
