used equipment – Should I expect a new-to-me large-format shutter to require maintenance?

I recently bought my first large format lens, a Fuji 180mm with Copal No. 1 Press Shutter, for about $180. The lens is great, but the timing mechanism of the shutter can be heard seizing up for speeds between 1/8 and 1/1 second.

From other discussions online, this doesn’t seem terribly unusual. What I’m not sure of is if I should expect these kinds of issues when buying a used lens. If I were to return the lens/shutter and purchase a new one, is it reasonable to expect a fully working shutter? Or are the shutters so old at this point that I should expect to perform some maintenance, no matter which one I end up with?
