metal gear mesh in a revo

[jokerjustin]

well i finally got my mamba combo for my revo and im super pleased with it!
but when i set my gear mesh. both the spur and pinion are metal.... it seems like its real rough to get rolling from a start by pushing it with my hand.... it also makes a good amount of noise..
i set the mesh by putting a business card between the gears and tightened from there.
it makes like a clicking noise every time the car is slowing down (free wheeling)..


would it be bad to put a little graphite powder on the gears?

i would also somehow like to lube my transmission... all metal gears except for the very last one.. (the gear that the center diff replaces).. can i also put graphite in here?

srry for so many questions but i dont wanna mess anything up.
