I'm fixing a Kowa SW that turns out to be a bit of a nightmare as issues pop up.
So I have taken everything apart and cleaned the shutter, aperture, etc... Now that I have put everything back I seem to have ok slow speeds 1.2s for 1s and 0.7 for 1/2s. But when I come to 1/30 I get 1/14, 1/60 is about 1/33, 1/125 is 1/52, so the camera will be more than +1EV.
Here is what it looked like before I cleaned them: (I always forget photos after)
As can be seen somebody before me has removed some corrosion. The camera had corrosion marks several places. So what I am wondering is if it the the spring that is weak or that I need to take it all apart and sand down the plates above and below the shutter blades.
Any advice much appreciated.
