Shutters open up but don't close of shutter is cocked.

I have a Welmy 6 x 6 with a terinar 1:3.5 lens. I have it apart and soaked it in rosinal fluid. I cock the shutter and the shutters stay open and don't close before it is fired. I notice when I cock the lens it seems like it is meant to open the shutter up anyways. I do have the lens apart and can submit a picture. Does anyone have any recommendations.

Almost certainly a shutter blade problem amd most likely due to old lubricant. After cleaning it, be sure to go over it again with clean naptha; if you let the old dirty naptha dry on the blades, the crud just redeposits.

I let the lens soak for a day, here is some pics

I let the lens soak a day in naptha and everything seems to fire fine, but when I cock the shutter is pulls the front shutter open and they stay open until the lever is pressed. When the shutter is cocked are they supposed to slide back down. I think someone didn't correctly put the spring the right way.

It still sounds to me as if you didn't get all the crud out. Did you just flood it and then let it dry? That won't do it; the crud just redeposits when the solvent dries. You have to flood it several times and let it drip between floodings. Swab up whatever lighter fluid is on the shutter leaves when they are wet, and work the shutter occasionally, and then swab it out when it is wet. This is how to get the crud out. Oh, and don't use alcohol for this; use naptha. Alcohol can contain up to 30% impurities, including gums, resins, and balsams. The idea is to get that kind of thing out of the camera.

If you are sure it is clean, and it is still sticking, then try this: Put a little Nye watch oil or Hoppes gun oil on all the pivot points. About what you can lift with the point of a needle should do it. It could be that you have removed all the oil and it just isn't working as it should due to friction between the dry parts.
