On my last outing I was a little too rough on my cat. I tried taking too steep of a hill and got it stuck on its side. It ran for at most 5 minutes before I killed it to prevent damage. It stayed like this for an hour to three hours. We decided to flip it over by pushing it to get it on all four wheels, which took at most ten minutes. Where it sat for about six hours. The next day I found some people who helped me pull it out and back to the truck. When I got home I found a small amount of gas in the oil, so I changed the oil and the filter. I took the carb off and cleaned it too. I found some water in the gas, likely from washing it at home. So I flushed the tank. I did remove the plug and turn it over a few times to make sure water did not find its way there. Now when I fire it up and it is cold I have no smoke, but after it warms up white smoke comes out of the exhaust. What should I check?
