Hello everyone!  I have a problem with the pneumatic stack of a standard
player action: too much vacuum is lost in the secondary valves system.
I made a new facing on the valves and regulated it with 1.2 mm [0.047
inch], but with pedal suction the valves are not sealing to the brass
flanges!  What's wrong?
