Anybody ever overhauled one of these exage rapidfire shifters? It's on a vintage mountain bike, I think the part # is ST-M050. The front one was sticky and only hit a few of the gears. I opened 'er up and now it won't catch / click at all.
This is why I prefer friction shifters and I would throw a set on this bike but I'll probably be passing it along to a friend who wants to get into riding a bit. Is it toast or is there a trick to getting it 'pre-loaded' / re-sprung when you attach the bottom part back onto the brake lever mount?
These pictures aren't mine, but they're the same part. Just a visual aid:
