Wood and Steel Posted June 19 Report Share Posted June 19 Last December I had an ignition issue that this forum helped me trace down to a rotor short. I replaced it with an old spare I had around, and haven't had an issue since. Well, I was out running some errands yesterday, and I lost all spark again. With some troubleshooting, I determined it was the rotor yet again. Luckily I had a new spare, so I was able to get back on the road, but I wouldn't think a rotor would fail that quickly. This was a rotor off a spare engine I picked, so I'm not sure when or where it was manufactured. I didn't see any carbon buildup on it, or cracks in the plastic. So, what would cause two rotors to fail in such a short amount of time? Quote Link to comment Share on other sites More sharing options...
Sniper Posted June 19 Report Share Posted June 19 Depends on what failed. Can you shoot a pic of that for us? Quote Link to comment Share on other sites More sharing options...
Los_Control Posted June 19 Report Share Posted June 19 Exactly what failed? If the rotor button is burned off and the spark has to jump too far ..... you got some kind of aftermarket coil pushing too much volts through a stock rotor. My last rotor failure was a cheap plastic body that wore out and allow too much slop in the timing ..... How do yours fail? Quote Link to comment Share on other sites More sharing options...
Wood and Steel Posted June 20 Author Report Share Posted June 20 It seems to be shorting, but I don't see any carbon buildup or broken plastic. It still fit tight onto the shaft. I will get a pick when/if I can, but I'm not sure what I did with it. Hopefully I didn't pitch it already. Quote Link to comment Share on other sites More sharing options...
