I have a 2003 700 Pro X and this last weekend I ran into a problem. The machine started 2nd pull in -20 F weather, so I was pretty impressed. Then I ran it around the parking lot and let it idle for a couple minutes. Then the machine died. I went to start it and it took me quite a bit of pulls (like it was flooded). As i was pulling I noticed gas coming out of the overflow on top of the Carb. Once the sled started running, gas was continually coming out of the overflow. The sled sounded fine and seemed to run ok (though I never opened it up, just put it on the trailer).
So now I have it in my garage. I am going to clean out the Power Valves and the Carbs. I have heard that the problem might be my power valve could be sticking, or my Carb seat might need to be cleaned/replaced. Does anyone here have any ideas or suggestions about this? Has anyone run into this problem before?
I would appreciate any help/advice.
