Hi, I’m having a problem with my generator.I recently changed points,condenser,and plugs.It was running good. Was using it during power outage and after about an hour it died like I hit kill switch.Checked spark at plugs and It gets one spark each time I hit start switch but nothing as I let it keep cranking.Replaced coil, still same thing . Opened control box and tested voltage at switch and relay and found no problem.Then I checked for spark again and it started working again. Ran it several more times (maybe 2 hours running time.Started it again today, it ran about ten minutes and shut down. I get one spark then nothing. I have 12 volts at points and at terminal posts on coil. If anybody has an idea I’d appreciate it.
