I bought my quad in sept. It has ran fine all fall while hunting and everything. I took it up north couple days ago in a snow storm to go ice fishing. The wheelers got all full of snow on the 2hr drive but started right up. I let it warm up while we got bait and all (i'd say it ran for 15min) before unloading it and when I hit the throttle it died. started right back up and idle fine. touch the throttle and dye...and i notice when i touch the throttle the engine light came on. i do this a couple of times and always the same result. only way i could get it back on the trailer is to feather the throttle and that barely worked. Had to ride out on the back of my buddies yamaha....
