Hi there, I'm relatively new to snowmobiles, especially anything newer than a 71 Ski Doo 399. We have a 94 650 rxl, and it won't run. The story(as I was told it)goes, the riders were stuck in a ditch, they shut it off, and when we went to restart it (after it was pulled out) , it wouldn't run. any Ideas on where to start? I didn't get to spend much time on it today , as the machine is outside and it's cold. I'm just looking for some ideas, and any help would be great. Thanks!
