My 8N died today as I was heading down the road. Luckily I was able to coast down the hill until there was a shoulder. Climbed off and checked my fuel flow and pulled a plug to check for spark. No spark. I was thinking it was perhaps the ignition coil as I walked the 30 minutes back to the house. Got in the truck and headed back to the tractor and tried cranking it. It cranked right up! This made me think maybe there was a thermal issue with the coil(??) since it cooled down a bit, but then it died after running maybe 30 seconds. Pulled a plug again, no spark. Pulled the coil wire off the distributor cap, had spark. So....is it worth it to go for the cheap fix and replace my points/button/cap? Or is this indicative of something more sinister, like the whole distributor????
