Re: engine painting
I'm assuming you have a Chinese 2 stroke engine?
Paint it. It won't hurt a thing and contrary to what you might think it doesn't need to be high temperature paint. I've used Dupli-Color automotive spray paint as well as other paints with complete success. I would recommend a gasoline compatable paint or a clear coat that will be uneffected by gas.
Light colors will darken a little near the exhaust port if you paint the cylinder. You need to make sure the engine is clean and oil free before painting. Paint won't stick to an oily surface.
