carbon on rotors
hey everyone...
my 12a is in pieces and i was wondering what i should use to get the carbon off my rotors? the factory manual says i have to be careful with the surface so any ideas?
i figure i'd rather be safe than sorry...thanks everyone!

ATF is crap.
Get a bucket of carburator cleaner, the kind you use to "dunk" a carb. One rotor should fit in the bucket at a time. Remove all of the rotor seals (especially if you plan on reusing the oil control O-rings) and springs (make sure to carefully note where they came from, using the numbers mazda stamped in to the rotor sides) and put the rotor in overnight. Next day, you'll have a nice clean rotor.
We used the carb dunk for cleaning piston/rod assemblies at one place i worked. The solvent was black from all of the dissolved carbon, but it would still clean a set of pistons like you wouldn't believe. A quick wash in the normal parts cleaner and they're ready for new rings and bearings, no tedious scrubbing.
Two notes - the solvent smells NASTY - fortunately the can has a lid. And don't put anything plastic or rubber that you care about in there, 'cos it won't come back out

Dunno why they say that? I know on the side seals you need to mic them so you know if they are worn unevenly that will make a difference... Best thing to do is use ALL new parts, unless you wanna do thuis again soon.

Make sure you get the napa carb cleaner that has the long warning of a basic summry of doing anything with this stuff will kill you. That eats just about anything off metal...

Yes. NAPA carb cleaner is the nastiest stuff you can get in a spray can. Still not as good as the buckets of carb dip though. But some things just won't fit in a bucket
The oil seal springs are different for the front-facing side vs. the rear-facing side. This is because they are directional and keep the seal from spinning on the rotor as it wobbles around its orbital path.
Beyond that, I wouldn't say you're SCREWED. You could still pop it back together but you'd have to recheck all the clearances. Unfortunately, it probably won't run as well as it used to.
