I bought the RD6800 in May of 2010. I have used it maybe 6 hrs total. Went to start it today and the pull cord locked up at about 3 inches. I started to check things out and it seems I have gas flowing into my oil tank. As I drained the gas and oil through the oil tank/drain I watched the fuel gauge go down. This was the first tank of gas it has ever had!! My question to all reading this is: has anyone ever heard of this before and what should I do?
