Yeah, as I noted in previous response, if you replaced the originals
which were undoubtedly either brass or bronze w/ ordinary steel they may
well be at least part of the problem. Pulling on seat back out and
looking will answer that question faster than posting here... :)
If putting a new washer on is all that's been changed, it's unlikely
there's a lot of additional new rust although as noted elsewhere having
opened a system is likely to break up old sediment which will take some
time to either reattach internally or get flushed out.
Better to swap out steel screws anyway as they will eventually rust and
next time need to replace washer will be more difficult to get them out
w/o damage.
