Water in air cooled engine oil?

There is water in the oil of my engine drive welder (lincoln ranger 8 to be exact) how did it get there since it is air cooled and how do I get rid of it. It also has a hard time cranking if it sits in rain uncovered and spits water out of the exhaust when it is turning over ,but how is it leaking into the oil from the exhaust? Is that possible?Water in air cooled engine oil?

sits in the rain uncoverd is why so now drain the oil really and throw a can over pipe or buy a cover for it really easy a old coffee can yes possible if its rains a lot and you dont crank it much more rain more water sure you can buy a flap or the pipe but a can wil do it
