That’s my best guess, hopefully you’ll prove me wrong. Please let us know what you find.

Also before this it only said that happens to OHV while this is a flathead motor but I'm not positive on that
you know if you were to post the model type and code # it would cut out a lot of the guess work.

That carb has the fuel pump built into the carb. and the diaphragm could have a hole in it drawing fuel into the crank case. Did you change the oil? It could be too thin and getting past the rings and causing it to smoke and use oil. It could also be the crank case breather blowing oil into the carb. through the breather tube.
