Help...my friend has a Yamaha Grizley 660 and it suddenly had lots of fuel in the oil. we drained and flushed it then realized that the air box was full of fuel as well. Seems to me to be a carb problem, maybe the choke is stuck or something. When we restarted it the thing was smoking white smoke so we shut it down. Anyone have any experience with these issues and or the cause?
