I am using the original plug in there, I have tried to swap it out with the other NR turbo plugs I have but they all work the same so no lost element. I knew I should have taken it apart from new as I have heard stories about debris in motors, even NOVA's. Its a roto start motor so maybe the one way contacted the rod like that at some point in time since it directly connects to the rod. I am using the RB two stage air filter and the LST fuel filter. I hope that cleaning it out and rebuilding everything including the carb works.
