    Well now I know why I couldn't get my sled started, but now I need to know why it's happening. If I start the sled, Shut it off again. And come back 3 hours later, it's flooded. I have to pin the throttle in order for it to start. Then when I get it running, it spits a very dark mix of oil and gas out of the pipe/can joint. Then if you take off the pipe, you can dump about a cup full of the oil gas mix out of it. So the flow of gas never stops. The carbs don't close. I already had the carbs off once today, the floats aren't sticking. So what else would make it do this? Sled runs great once running. But if you let it sit, it flat out floods it self. Need some help here please.

    Sounds like the needle and seat need to be replaced.

    ^^ Yup, in the meantime, turn off your gas line so it will prevent leakage. get em replaced asap though.

    Bad needle and seat and/or your diaphram in the fuel pump is starting to not hold pressure back.

    I would bet needle and seat, also like stated check the diaphragm. I had a tractor that had the float sticking, and the needle was sticking. I dumped a good 3 cups of gas out of the bottom of the air intake.

    needle and seat,or the fuel pump could need a rebuild, it could be letting fuel enter the crankcase thru the pulse line.Dont get aftermarket parts either,get geniune mikuni.i heard not having good luck with the cheaper stuff.

    take you're carbs off ,turn them upside down attach a piece of hose to the inlet nipple and useing you're own hot air ,blow into the hose ,if you cannot get them to open ,probally are good if they do not hold pressure ,need to replace them (needles &seats)
