Starter button is intermittant.

Starter switch probly needs cleaning    Is this hard to do?    Watched one video on starter switch maintenance and looks doable.  Any pittfalls i will encounter?

So easy even I could do it. Just be extremely cautious about losing the tiny spring or the stainless ball.

   Yes, it's pretty easy.  I've done it 3 times myself.   
   The last time, I noticed how the black plastic body containing the fixed contacts was sticking up just a little above the plane of the copper contacts (which showed no scoring at all).    So I carefully filed down the plastic body until it was level with the contacts.  It has never been intermittant any more. 
   I think that's one of the problems with these switches. 
   The other is the part of the button with the spring loaded sheet copper contactor jumper.   On mine, this had some nylon molding flashings on it which were keeping the spring loaded contact bar from moving up and down freely.  These have been trimmed off with an xacto knife.

I just finished.    Follow the houtube video and it was easy peasey.   Contact surfaces had quite a lot of green corrosion.  Cleanded them up and she cranked right up

Hopefully you made sure the brass contacts were free to bounce up and down on their little spring. If not they will be in light contact with the pickups and that green corrosion will return quickly
