Finally, my Aeolian Weber 192X is restored, and it seems to work just
fine except of a few things: All notes does repetition rapidly both on
high and low suction, although the piano action gets problems on the
softest levels. (On the workbench it does repetition much faster than
in the piano, and I have also regulated it to the piano action.)

My piano techinican has changed the tuning pins and strings fixed the
soundboard, and also regulated the action some, but not fully.
(Complete disassembly and reassembly wasn't included in the job I paid
for.) Since the pneumatic repetition is rapid on the workbench even at
very soft levels, and the regulation to the piano action should be
good, should I go for the extra job that the piano technican
offers/advices me to, or may the explanation be too much pouch
leakage?  (See below)

(When hitting a key slowly and softly, the notes tend to play two times
sometimes, and it didn't do that before the piano technician adjusted
the action. When the action doesn't follow the pneumatic action, I can
still see the valvetops working rapidly, and the pneumatics trying to
play rapidly without the action responding properly at soft levels.
Valve travel, and the smoothness of the pneumatic movement does not
seem to be a problem)

What's seems even more trickier is the bleed size vs. the new pocuhes
installed. The notes dies on soft playing, e.g. they hit, and does
repetition OK, but won't last very long. This sometimes causes double
notes, as mentioned above by very soft playing.  The new pouches are
more leakier than the old ones, and I didn't seal them with rubber
cement, since I was unsure if the types (shoe repair gum) I find in the
stores won't get hard, stiffening the pouches.

May I safely thin this shoe cement with acetone, and add a couple of
layers on the pouches, or should I try it some some spare pouches, and
wait some months to test it first? I have got one type that one may add
into cracks into the rubber and also as glue, and it should dry for 16
or more hours in a humid atmosphere.  I also have access to bicycle's
tyre mending kit glue,  that is a vulcanisationing glue, may this
eventually be used? I tried this on a couple of spare pouches which
still are soft and also completely airtight, but one month of testing
time is maybe to little?

I have however sealed and preserved the pouches with mink oil, and pure
silicone, and I have access to the pouches through the front cloth, for
future resealing.

This seem not to be as effective as rubber sealing.  Should I be
satisfied with this, and instead make the bleeds smaller, and
eventually how do I do that? The bleeds are small green celluloid
plates. Could there be a leakage around these plates, which I could
tighten with thin shellac?

Could I use tiny round coloured  paper labels and prick a hole in them,
or do I have to drill them out, and add new plates?
