Nope, it's a new plug.
This is my second actually, my 1st RC was the older rustler. But I'm still horrible at tuning. Sometimes if I'm lucky it will start, then sometimes it won't. I read somewhere and accordong to the reading, my low speed was set too lean, I richened it a bit, and it works alot better now. But after a few minutes of just driving around (not even WOT) it will die. I kinda play with the highspeed for best results, but still can't get it to run the way I want.

About how long does it usually take someone to learn to tune decently?? I'm willing to work towards it for as long as needed, does it just depend on the person??
