when this motor sits up for a while the oil gets into the cylinders. I have to take the plugs out and blow the oil out. It is a oil injected motor, so I think I can pre mix to to bypass the problem, but I would like to know how the oil gets into the cylinders. If I premix do I need to disconnect the oil tank? has anyone ever run into this problem? Any help would be greatly appreciated. Thanks guys
