So I drove the M715 about a week ago and it cut off on me while I was driving down the road. It would turn over it just wouldnt fire. I assumed it was the coil so I replaced it. Still no start. I then checked the point and made sure it had spark all the way to the plug and it did. The points looked like they were bent a little, unsure why. So then I tried adjusting the timing and I had to turn the distributor all the way clockwise and I finally got it to start. it still sounds as though the timing is off but its running ok now. What would cause the timing to go way off like that? Was wondering if maybe the timing chain may have skipped. Not sure. Any thoughts?
