After months of trying to figure out what was wrong with my ski, we appear to finally have the problems resolved. Last fall it started running erratically, and it was determined that the fuel sensor float didn't, causing the ski to go in to limp mode. I replaced the sensor with a new one, and the ski ran worse, though the limp mode was gone. After a couple of wot shut downs, a compression check revealed problems necessitating a rebuild, including a new sbt crank. The carbs were clean, the oil pump pumped, all looked well. However, when I got it back, it still exhibited lean running problems. We started hunting for fuel supply problems, replacing the fuel pump and checking everything.
It turns out that the new fuel sensor was bad, and not sealing at the top where the aluminum tube joins the flange at the top of the unit! As a result, it was sucking a lot of air, and starving the carbs especially at higher rpms. On top of that, I have since discovered that there is a float repair kit available for these sensors that is about 20$ that would have fixed my sensor. My dealer warrantied the part, but there is still no word from them on whether or not Polaris will help with the considerable expense I have incurred as a result. By the way, the float repair kit part number should be 2872860, as opposed to the fuel sensor which is 2410058.
Many thanks to those on this board who offered assistance, and especially to Tim at Performance Motorsports in Ft. Wayne IN. Considering the small purchase I made from him, he went way out of his way to help me solve this problem.
