Hi, I'm a new transfer from ThumperTalk. I have a 2002 Polaris Sportsman 90 that up until a couple of days ago ran pretty good, but was occasionally hard to start. It would flood and load up, run for a few seconds and cut off. The spark seemed kind of weak. Now it doesn't have any spark at all. I have a new CDI box, which changed nothing, and the thing has a brand new carb (electric choke version). It hasn't run much since I did the top end, so low compression is out as a starting problem. The mechanics at the local shop were young kids, and really didn't seem to know anything. I do have a manual, but it isn't real helpful. I will be checking back often, but will be at AMA Vintage Days this weekend.
