OK we are back in business (see photo)!
I couldn't find an OEM starter button assembly separate, so I had to buy the whole new right hand switch. They have changed the starter button design, so my Plan B of just switching out the starter button didn't work. Plan C was to install the new right hand switch, but to replace the lavender kill switch with the original red kill switch. It took a little surgery with small tools, but I got it out. Thanks for all your help, on to the next challenge!
