Mini quad bike keeps cutting out.?

I'm no mechanic, but I've had the same experience with dirtbikes, quads and snowmobiles. They would idle fine, but when you touch the gas they stall. Everything worked out fine if I let them idle for a while, then I could slowly work the throttle. By the time it was nice and warmed up it would run perfectly. It might take a bit longer to get riding but its the easiest fix I know of. Just let them warm up real good (5 min till you try the throttle).
