I'm wanting to have Green Meanie, my '73 wagon, run better. I was advised to have the points replaced. Kimmy kindly showed me what points are but I'm still daft about it all, so this morning I perused my trusty(?) Chilton's book and straight from another book (The Great Book Of Dumb And Stupid Questions) comes this query: What is the high-tension wire in relation to "Disconnect the high-tension wire from the coil and unsnap distributor cap..."? I can't even start a project without facts! lol. Also, what do bad points look like? Thank you for your help.
