So just put my motor together got it running and ive noticed that the crank case vent that goes to my intake is whistling and the idle is terrible. If i remove the hose it seems to run better but i know that is not good, so i checked out the hose and it seems to be fine so im kind of lost here.. also i pulled the plugs and they were very black and one actually was wet/ black. any advice would be helpful. thanks!
