Hi: I am looking for some help. I just bought a 2004 Can Am 400 quad that had sat for 2-3 years. I can start it if I spray some gas into the carb but it only runs a few seconds. I haven't been able to get it to continue. Any advice on what the problem might be and how I might follow it would be very much appreciated. It had about a quart of gas in the gas tank when I got it. I siphoned that out and put in new gas. This is my first quad so I'm quite new to this.
