Chasing same issues again any ideas? ‘34

[34 fordor owner]

I rehooked up my temp tank to ensure I’m getting fuel but when I hit the starter button it’s not spinning over fast enough. Got 6v at the starter button but clearly not making it to the starter. It was popping a little so maybe with more turn power it would start up. Guess my starter switch is finally given out. I have taken it off 3 times now and cleaned the contacts and no success there. I’m going to look at getting one of those and then pick up again.
