Alright I got a new issue, went to river yesterday and rode a good 4 hours. Trail riding, no water. We stopped and took a break and when we left I got on it, as I was accelerating it started to fall on its face....like it was out of gas. So I started doing simple checks....fuel valve, has gas, power switch, plug wire and found the carburetor had come lose from the intake. Not a big gap, but definitely lose so I thought well perhaps it was sucking air. So I fixed that and now i cant get it to restart. I have fire, and have cleaned the tank as i found the gas had a bad smell. I am wondering what I should check next, it getting fuel and fire. That makes me think timing? It's odd that it just one second to the next it just died. Any suggestions would be greatly appreciated.
