Carb Cleaner is not for long term storage

About two weeks ago, I pulled my Tillotson cores out of the tub of toxic methyl chloride carb cleaner. They'd been sitting in there since, oh, last May.

Lots of parts were ruined. Both floats at the very least.

The pot metal pieces looked OK, but the brass parts seemed to have dissociated.

So, yes, let the stuff do it's work, but a month is probably as long as you should let carb parts sit in this witches brew.
