I've ridden every sled out there and finally bought myself a 2011 Summit X 600 E-Tec. I did not want electric start and loved the way the showroom sled started in one easy pull. However, my sled does not start in one pull when it's been run for a while. Cold start is one pull. Warm start is 2 or more pulls depending on how long it's been sitting. I am female and am good for about 3 - 4 pulls, after that I have to get a man to start it which I hate (no offence). I rode an 800 E-Tec and started it all day, every time in one pull so I know that I can pull hard enough. The dealer is stumped and has been in contact with Skidoo, who they say are also stumped. Their fix is to put electric start on it which is NOT what I want. Has anyone else heard of this problem? Does anyone have any suggestions? Any advice would be greatly appreciated!
