Okay, got my carbs synched and the difference was immediate and fantastic, but my battery is terminal I think. (Pun intentional). I have a problem and I don't know how to fix it. The problem is that the negative terminal was corroded and now the nut that holds the screw is spinning freely inside the terminal. I've cleaned it up pretty good but the screw is in a nether region between loose and tight and I can't figure out how to get in there to hold the nut in place. The cable keeps me from moving the battery more than an inch or two in any direction. Any ideas on what to use to get it out?
