I just picked up a 2000 600 RMK with only 350 miles on it. It runs great with a small problem after it has been shut down over night. It floods or fouls the plugs easily. When I first attempt to start it the plugs seem to be fouled. I take them out & clean them up and the machine fires right up. I run 88 or 90 octane fuel. Does anyone have any ideas or is it just the trashy fuel in this neighborhood. Fuel is a concern for this area.
