So it looks like you need to flush that motor with more than just water some sort of Sullivan that gets rid of all the corrosion next you're going to want to check all your cooling hoses water routes make sure it's venting properly out of the eyelets at the back engine compartment highest and make sure your oil is clear lines next you're going to want to turn your carburetor low screw all the way in and then turn it out one full out turn in your idle till you're hitting 1800 RPM relatively fast idle
