Oil aroiund glow plug and coming out of exhaust pipe - New to nitro and experienced these two problems while running my Revo 3.3. Both issues starting occuring when I ran my truck the day after conducting the post-run mainenance as outlined by the Traxxas DVD/literture. I think I fixed the oil leaking out of the GP area by tightening the GP. I ended up burning that GP and there was a load of gunk all over the inide of the engine cooling head. As for oil coming from the pipe, I think I'm running things a bit rich. It was getting dark outside and didn't have a chance to make further adjustments. Any suggestions or help would be greatly appreciated. Thanks.
