I have some random Chinese brand quad (the only labels I see say LongChang, Zhongshen, and Viking 250). I've already hunted the internet trying to find the company to get an Owner's Manual. Does anyone know a) what brand it is, b)where (if at all) to find the manual, or c) how to fix the idling problem I am having? I can't, for the life of me, figure how to get the darn thing to idle. It runs fine, just so long as I keep the throttle going. I'd like to not have to carry around a spare gas can every time I ride. And, lastly, I'd like to give her a tune up, but I kinda need some information before I start draining and filling things. Any help would be greatly appreciated.
