Got a hold of some old bike which was destined for a landfill, and I'm trying to make it a project to get it road-worthy again.
I have some questions off the top of my head:
1.) Tires - they're old, but I'm hoping they're serviceable. Thing is, they have all kinds of crud crusted on them, and if I can help it, I'd rather they not look totally ugly. It looks like it might just be old mud which solidified really hard. I tried soaking the tires in water and then using a stiff brush to scrub them, but was surprised when I couldn't seem to get all of the the crusty bits off the tires. The mud or whatever is just hardpacked on there really good. Any ideas for getting the tires nice and pretty and clean so it's more presentable?
2.) Chain -- was trying to break it to clean it, and accidentally managed to break off part of one of the outer plates. I can still push the pin back into position to rejoin it, and I think I can get the stiff link out if I work it long enough. My question is, does the broken plate on the chain pose any danger in terms of the chain breaking or anything? If it'll still work fine, I'm not in a hurry to replace it. But do I need to replace it entirely?

3.) Adjustable cup -- I want to overhaul the BB, but I haven't worked with this particular type of adjustable cup yet. I don't see any pin holes or anything, just hexagonal flats. What is the tool I'm supposed to be using to adjust it? Should I just use an adjustable crescent wrench? The flats are pretty slim, so I would need to be careful to avoid the crescent wrench slipping around. Is there a better tool, or should I just wing it with the crescent?
4.) Fixed cup -- if I need to move this, due to damage etc, which way will I need to turn it? The bike is a made-in-Taiwan Schwinn pink Sierra, 24" youth MTB. Am I safe to assume that it's not made to Italian or French standards and will have the reverse thread (clockwise to loosen) like most common BB's?
Thanks in advance!
