i've been noticing lately that my manifold on the PTO side is starting to get really oily. why would this be happening plugs look the same? then tonight i took my sled for a ride and it was running okay and all of a sudden it wouldn't idle and it lost all power after i climbed this little hill with a drift on top. wouldn't run on one side, changed plugs and still wouldn't run. i'm wondering if maybe the floats are stuck and flooding it. i run the sled for a bit and it ran like sh*t and when i shut it off there was gas dripping from the manifold. dose any one know what could be happening or causing this? help is appreciated !

thanks
