My T-Maxx's 2.5 head might be bad
Hey grampi, I had one do that to me.There was just a very light inperfection around the glow plug hole.I took off the head and put a small buffing wheel on my cordless drill and buffed on it lightly for a while and it worked great. Maybe it will work for you maybe it wont. Nothing to lose since you orderd one.Beats waiting on other to come in the mail...
