No, the problem we are having is I left the parts in the vinegar too long. I ordered two cups from Superscale and that seemed to help, but I should have ordered two stems at the same time and I didn't. But, now that you mention it, I am suspicious.

I've been allowed to take my friends Mogul out many times, and have had to push her back in twice, because I have caused his superscale injector to become erratic and I can't get repair parts for it.

Never heard of nor used any such thing on any part of those engines. AND, would never want to be c...

The silver bearing solder you want is 95% tin, 5% silver. The hardware store stuff is 95% tin, 5% bismuth, or something like that, and is crap to use. The commercial names are Harris Sta-Bright, All State 430. Especially for brass or sstl, the liquid acid flux sold with those should be used. That a...
