    Question:  when was the last time you folks had your carbs properly inspected (to include disassembly)?  It really ought to be done every 200 hours.

    About 30 hours ago and 2020.

    A flooded carb will overflow through the carb jets into the carb throat.
    If your engine sits anywhere near level in the hanger, it is possible that some amount of the fuel flooded the intake manifold and there is a 50% chance that when the engine stopped that one of the intake valves on that side stopped in the open position. 
    The fuel would flow into the cylinder and, over the course of hours, slowly leaked through the gap in the piston rings in the crankcase.
    It would be recommended that you check your Oil for fuel contamination.

    "Burp" the crankcase as usual and then check the Oil Tank for the smell of fuel.
    If the Oil Tank is found to be Above the "Full" mark,  You might be looking at 4 Quarts of Oil Plus a Pint of Gasoline.

    Something to think about.

    Good thought on fuel in the oil,

    In my case, the engine has less than 20 hours on it, but over 4 years which I think is the main problem - lack of use, and fuel was left in there for many months before it was drained.
