Sled ran wonderful all weekend long and Sunday right at the end of the day it started running like crap. I drained the gas today and filled it with new gas which helped with the really low idle it started having at the end of the day. Now when it idles and i hold it to the bar from idle it bogs and dies. I've cleaned the rave valves checked the Dpm with a 9 volt battery and that is working. What else could it be!?! Carbs seem okay but haven't taken them apart to check if anything is in there. Ran out of time today.
