Just recently (today) cleaned the carbs on my buddies Polaris 680 Ultra due to it not wanting to start easily and a bad idle. So I pulled them all out and cleaned them all. Set the screws back in the proper adjustment as they were before cleaning them. Now it's running super lean (smoking way more than it should) and cannot get a smooth idle to save my life. He is wanting to get his sled back asap for the snow that's coming and I'm exhausted on options. Can anyone help me with some ideas or what I can do to get this sled so it'll idle and not run so lean! Thanks!

sounds like pilot jets are plugged you need to clean them with a wire , you also should check the compression
