The oil is from the engine and is exiting through the exhaust as it is expected to. There is probably an excess because the engine was properly fogged when it was stored.​

You should get a new water pump impeller to start with, then check the thermostat. If the carbon is looking heavy on the plugs, its probably time to decarb the engine.
