Blown Head Gasket
This was an OHV motor so in order to get to the head, you must remove the valve cover and remove the push rods. Remove all four head bolts in an even star pattern. Remove the old gasket and scrape all remaining gasket gunk. Put new gasket on and tighten head back on with an even star pattern. Slide push rods back in and adjust valves to .004 of an inch and put valve cover back on and start it up!
