I have an 1992 EXT 550 Arctic Cat and it seems to have some problems. I picked it up about 4 weeks ago and the owner stated that it had a few problems but nothing big. It bogs like crazy to the point where it won't even move out of the garage. Track spins when lifted, so it is not a belt problem. Took apart the carburetors and the cable that controls the choke input was stuck on full in one. I just took out the cable because there is another in the other carb. Was able to ride it for an hour afterwards and it ran perfectly, but it started bogging really bad again like it was before. Took a look at the carbs again and it looks like one of the boots is starting to go out. Woulden't that just make it a bit lean instead of bogging it down and losing power? I have no clue on what to do, and I'm not really wanting to bring it to the mechanic because the service would cost more than I payed for the sled. Do any of you have ideas on what to do next? Thank you so much.
