He purchased a used RS4, and when we got went to look at it, it looked brand spanking new. Even the engine did not have a speck of dirt. Anyways, apparently the engine had been broken in already. We get it home, and it runs like garbage. I suspect it has never been broken in at all. So, now I would like to put the needles to the stock positions and start a break in process. Thing is, I don't think it's the stock RTR engine. It's says NEO on it, and that's it. Here are some pictures. Maybe someone can help me out.
