we recently bought a new chuck wagon ..the first time we checked the oil it came running out and looked like mud...so my husband changed the oil and within a few days checked it again and it was already starting to look "muddy" or milky, it is thin and smells like gas.....we called the dealer, they said all it could be is the carburetor, there are no adjustments on the carb...so they put a new carburetor on it and it still is doing it....any ideas on what this could be or anyone with a chuck wagon ever have this problem? other than that we love the machine, but we would really like to resolve this problem...any ideas would be greatly appreciated
