Shutter curtain timing issue that's driving me nuts

I mean, on this old rangefinder, the second curtain is lagging behind the first. Idk if it's a tension spring problem or the curtains themselves. Maybe it's just me, but adjusting the gears hasn't helped. Any simple fixes I might be missing?

Shutter curtains on old rangefinders can be such a pain. I mean, I've had similar lagging issues with my own gear, and it's always a headache. Maybe it's just me, but those tension springs seem to wear out over time. Adjusting gears sometimes feels like guessing, especially without the right tools. Hope you find a simple fix, but idk, these things can be tricky. Solidarity from another vintage camera struggler.

Did you check if the curtain material is sticking to itself? I mean, I had that happen on my Leica and a light rub with isopropyl alcohol on a q-tip helped, since sometimes the old lubricant gets gummy and causes lag. Idk, it might be worth a shot before taking apart the gears.

About the curtain sticking, my friend cleaned his with alcohol and it sped right up.
