My flaps are working but have a problem. The handle wants to spring up after each stroke. Used to be a solid four strokes to full flaps with no handle spring back. Now about eight with a lot of spring back with each stroke. Handle wants to stay sprung up with any flap setting. I replaced o-rings two years ago and flaps seemed fine until recently. When I release the latch they come up as usual. No sign of fluid leakage and flaps stay down once set.

When I got my '68 M20C a few months ago, my flap handle worked nicely - 2 pumps for takeoff setting, 2-3 more for full. Exactly what the POH says. The release lever was very stiff, but then a local MSC simply lubed the cable, and it worked perfectly too. Now suddenly (on first solo after finishing 10 hrs transition training, of course), it takes 3-4 rapid pumps to get any back pressure behind the handle and have flaps start coming down. Then it takes 6-7 pumps to get them down to full. They seem to stay down ok and will still come up at appropriate speed subsequently. I've read various stuff on other posts regarding leaks, bleeding the system, including trying to get air out by various strategies. My questions are (1) Did I do anything to cause this problem? (2) What, if anything, I should try to do myself here before flying back to MSC. Dealing repeatedly with early squawks is getting old, and I really just want to fly it for a while to get my skills honed.
