My yashica fx 2 has this issues where the mirror sticks every few shots because of some mechanical issue. I decided to open it up to see what was going on and I saw these two ratchets that dont move or do anything when taking pictures. I tightened the rightmost one about 4 turns because it seemed loose and my shutter sticking issues fixed. It does make a strange noise and has a slight mirror return delay sometimes which I think is it overcoming the sticking. It is definitely a mechanical issue and not sticky foam or anything. Only reason I am asking here is because I read that the gears are responsible for film advance and spacing. Any help is appreciated im new to this
