I just installed a new leather washer on an old Silca frame pump. Thanks to Paulie Davis for the washer. I smeared it with olive oil, a new one for me, since I had always used grease before, and installed it. The pump has the nice metal Campagnolo head. When I cover the hole in the head (the pump head, not my head) with my thumb, and draw the plunger back, no air comes in. If I let the plunger go, it slides back toward the pump body.
What should I do? Please do not advise me to ditch the Silca in favor of a Zefal. I want to get this one working.
Thanks,
