A week ago I went 50 kms up into the alpine, after letting my sled (2000 summit 700) sit for a few hours it started first pull but shut off two seconds later. After an hour of trying different things (swapping plugs, dipping plugs, choke no choke, checking electrical etc...) It would not start, couldn't tell in the daylight if it would spark or not. In the last week my friends have gone up multiple times to try and tow it out with 2 XP's. It is stuck at the bottom of a huge hill in Seagrams, Whistler BC. The best case senerio is for me to get it running and ride it out. any suggestions on what to do?
