we still haven't fix the problem but we have found out more about the problem it will run fine for about 45 minutes then start to run bad we can let it sit for a half an hour drive it and it will be fine for a bit if it doesn't get a rest then it just happens every minute or so it is very annoying but what weird is we can drive around on the trail in lo range for ever and not have a problem once we get on the road to go home it starts acting up. The plugs wires and cap and rotor are new so now I'm thinking it might be fuel but it happens so randomly. Should i rebuild the carb or what and info is great
