So i just put 7ish tanks through the new motor. I'm running 30% nitro and I'm running 0.4mm head shim instead of the factory 0.3mm, i seems to have it pretty much tuned. i read somewhere about it detonating or something and was wondering if this white stuff on the glow plug has anything to do with it or if i was just running a bit lean? is it suppose to look nice and gold like that, sign of rich I'm guessing? also the head didnt come with the new motor but its not that old itself.
