I have a few questions regarding maintenance on an NQ50, while I wait for some parts to arrive.
I don't have very much experience with two stroke engines, so I have also ordered a manual for it, but I love to tinker with this stuff. I removed the (what appears to be) transmission cover, and was fairly surprised to find a layer of black stuff (assumably carbon, but I'm not sure) covering just about every surface.
Is This a normal occurance?
A moped is a lot different than a lawn mower, (I expected the piston to be bigger) And I'm not quite sure how maintenance is done on one of these. Any answers or general tips would be greatly appreciated
