Hey everyone, I just picked up a nitro tc3 and it has a .15 os max engine in it. It only has about 1 gallon of 20% ran thru it but the internals are kinda browned up. It takes quite a few pulls to get it started but once it does start it runs like a raped ape! It has great compression also. I know I cleaned up the top of a piston before with some denatured alcohol and it started faster and ran better, but I was wondering if there is a way to properly do this or a tech secret floating around out there. I know the brown will come off also it's not really burned in if that makes sence.
Thanks
Jeff
