The shutter started acting up on my ZI Donata, after semi-dismantling it appeared to be the cocking-ring binding around the main body.
Seeing that it was part dismantled i put the lot into a small tub full of IPA, not the hoppy beer, but 90 odd % iso-alcohol.
That tub went into the ultrasonic cleaner full of generic cleaner. Smells like windolene, but 100 times more expensive?

Anyway, it all came out clean with minor debris and discolouring within the IPA.
Dried off and lubed up, i bought a watch oiling kit with small amounts of moebius oils & grease.

test-assembled and operated it now works fine; all speeds, T & B. Even the self timer is good.
it worked great before, so no real improvement other than back to where it was and no binding.

But, i have this wire-spring, that i don't think it sitting correctly? I think it may even have become distorted.
It's somewhat loose and sloppy on the pin it's wrapped around?

It doesn't seem to do anything now, i thought it was acted upon when the speed-ring was set to 200?
i have an image of the same spring on this site, but its different, so not sure?


A photo/description of how it should be would be great?
TIA.
 
That's the booster spring for the fastest speed setting. You haven't specified which shutter this is but on modern Compurs that spring would be a bit straighter. It's normal for it to be loose on the post. How is the fastest speed?
