Last summer we experienced major problems with our ski. It ran rough, would stall out and had little power. Upon investigation we found a small amount of oil in the air filter and a disconnected hose in the same area. We reconnected the hose and tried again with the same issues. As a test we ran it without the air filter and still the same. I'm moderately handy so I'm thinking it may have to go to the dealer if I cannot fix it myself. I'd like to avoid that expense if I can but don't really know where to start on my own. I'm thinking I may have a fuel filter issue as well, as the symptoms I have described are very similar to a post I read earlier. Any advice would be greatly appreciated.
