I've been reading a lot of your threads lately. It sounds like everyone on the east coast is getting the shaft by mother nature. Over here in Utah our mountains are still getting slammed. It's been a great sledding winter. I honeslty don't know how many times I've been out. That's not why I'm writing this. Needed to ask some questions about my sled. I just recently spent a ton of money on it and it's still not running great. I had one awesome day up in the mountains two weekends ago (I ride a 96 Polaris Ultra SP). Then, the next weekend I took it out and it died on me. The center cylinder seemed to be getting oversaturated with fuel. The other two get slightly saturated and then the stupid thing just stops working. It will bog for a second and then just die. Also, my low end is ALWAYS bogging. I'm not really sure what it could be. I ride in altitudes of 6500--9000 feet, so I'm up pretty high in the mountains. What could the problem be? Any ideas?
