I am working on a 1992 ski doo 583 rotax motor. I just cleaned the carbs because the sled was brought to me from a long stay on a farm. The carbs were nicely tarnished. So I cleaned then carbs thoroughly and reassembled the sled. I started ii and it ran and idled great. After I shut it down I tried restarting it and she was flooded, finally got the old dog going and noticed that gas was spewing out of the PTO side carb overflow tubes at a constant rate. Checked floats, they are freely moving and assembled correctly so I was wondering what I might be missing other than starting over and going through them again?
