Has anyone tried to rebuild the starter button on their naa? Mine quit making contact when I pushed it (if I ground the end of the wire it turns over) so I know it's the button. I removed it thinking I could just take it apart and clean it so it makes contact ,but I don't see how it comes apart. I see what I thought is a small snap ring on the part that pushes down into the shifter, but it is solid even though it isn't tight on the shaft. there is a small hole 180 degrees around from where the wire attaches approximately 1/8" in diameter ,but I can't see what it's for. I would rather rebuild this than buy a will fit piece of junk that may or may not work, been there done that too many times!!!!!! I've looked in all my books and online to see how it comes apart to no avail, Hope someone can help me on this .God Bless, Beth and Allen.
