I would surmise temperature has little or nothing to do with the sticky balls. I think it's related more to the ills of a toilet flush tank in a vacant house. Just simple stiction. Funny we all know all about this issue; must all be cheapos and own (or at one time borrowed and didn't return) the Skeets gauge. And don't be such a big Zero, Bill. Why set to a ring gauge when you can set the indy bezel to zip on the dial with the balls in the bore and read choke constriction the simple way: te-ehn, twen-ty, toity, foighty--yup 44 thou underbore.
