A couple of questions:
1 - does it help to put any kind of lubrication between the spur and pinion? I think I got a piece of gravel in there at some point because my steel pinion has some little dings in it. Kind of weird, because the spur looks fine. My spur/pinion make a lot of noise, although it seemed noisy before the gravel damage.
2 - Ive seen people soak belts in wd40 overnight to soften them, has anyone done that to their belts? I have the blue tamiya ones.
