any repair tips for a leaf shutter?

I have a couple of Retina Reflex IIIs with slow shutter blades (true
of almos all of them).

Are the blades sticky or the slow speeds? If the blades are sticky, I remove
the lens cells and carefully clean them with "lens cleaning fluid" I bought
in generic form from the camera store using a q-tip. You might have to
flood the blades with fuild, them wipe off the excess after working the
shutter. Never had one that didn't come around doing this. Do -not- use any
lube on the shutter blades, they are suposed to be dry. I don't like the
flooding the whole shutter deal as it washes out -all- the lubrication in
the shutter.

Is gummed shutter blades the sole cause of distorted shutter speeds? Do the
springs ever give out? I never leave my shutters cocked when I'm finished
with them. I know that is important. But do the springs still loose life
after enough useage?

I've never had to replace any parts to fix any of my old shutters. They all
came around with cleaning either the blades and clean and lube of the gear
train. As far as leaving them cocked, a well designed spring mechanism
isn't going to be damaged by leaving the spring in a compressed state.

"Distorted speeds" can be caused by either the timing mechinsim or sticky
blades. It's not hard to tell which it is by watching the shutter operate.

I have a couple of Retina Reflex IIIs with slow shutter blades (true
of almos all of them). Since most lenses with leaf shutters are MF
lenses, is there some long-lasting trick to make them come back to
life, such as using very fine graphite powder, or do I have to bite
the bullet and pay for a full shutter service from those competent to
service Compur shutters? Perhaps there are some current or ex-camera
repair people here who have worked on Compur leaf shutters who can
answer my question.

Many thanks for all the replies.
