I received my ebay Konica S2 today and the shutter will not fire and something in the RF rattles.

I am trying to remove the top plate. I cannot seem to figure out how to remove the re-wind knob. does to knob come off of the stem or does the entire stem have to come out?
 
I am not familiar with the Konica, but on most cameras, you put something like a popcicle stick, in the splines of the rewind shaft, where it engages the film spool, and turn the rewind knob counter clockwise to remove. With the knob off, you can usually leave the shaft in place. Some cameras have screws under the knob that you can't get to until after the knob is off.

This is typical KAS2 syndrome. Shutter blades are stuck due to dirt - can be cleaned up with lighter fluid moistened cotton swabs. RF mirror is fallen off it's place and rattles under top cover - mind you, in VF there is no yellow RF patch. Has to be position as close to original position as possible, after glue has hardened, RF has to be slightly (more or less) adjusted.

To remove rewind know, put something between in the and in cassette chamber (fit it, don't let rotate) and unscrew top part. Hope this helps.
 
I have opened up the camera and re-glued the RF mirror and adjusted the RF.
I cleaned the blades with lighter fluid but in the process I realized that if I pressed the shutter release several times in quick succession the the shutter would fire.
Also the blades do not seem to change aperture from f/1.8 to f/16.

Any ideas now?

Clean the aperture blades too, just like you did the shutter blades.
 
Well I spoke to Greg Weber at Weber Camera and he said that it is is in the firing mechanism. When these cameras were originally made they were lubricated with "whale oil"!!! He said even a very nice camera that has not been used much will eventually gum up and need a CLA. He also said if it has been used occasionally through the years it may not gum up as bad.
I have packed mine up and am sending it to him today to let him do a CLA and at the same time he will convert it to use the common 1.5v batteries and re-calibrate the meter to the 1.5v battery.
My S2 is such a clean camera I thought it is worth the $100.00 to let him clean and adjust it. Greg Weber at webercameras.com
