 You are correct about the cleaner attacking the bearing material. Question? Are
you using one of the "new" EPA friendly carb cleaners? These do not work nearly as
well as the older stuff does. Of course you can cure that with the addition of
methyl chloride to the cleaner. Agitation will speed the cleaning process up.
 Heat speeds up the process but also destroys the cleaner.

I have no doubt it is the EPA type. We are in California after all.
(Our toilets don't even work :-)) 

Where do you buy methyl chloride?
