But hey, at least you get potpouri, all I ever get is mouse crap and corn!
As for the compression -
First, I'd say measuring it by amount of wind passing one's finger isn't exactly an accurate measure! Remember these are very low compression engines to begin with. The difference between "perfect" and "not so good" might not be detectable with a finger.
I'd get a cheap compression gauge and check it before wasting any time with it.
But let's say the compression IS truly too low.
I'd dump a little oil in each spark plug hole and retest it. If compression comes up, you've got worn rings.
Pull the valve cover, crank the engine and watch each valve. If they're stuck, it should be pretty obvious that they aren't coming back up when the rockers lift.
If they appear to be working properly - then check the valve lash. (don't get all super accurate, just a ballpark check) The valves could be coming back up to close, but never making it all the way to seat.
It's unlikely they'd be worn so bad that they'd be no compression - the engine would have stopped working before they got that bad. BUT it is possible somebody messed around with them and cranked them too far down.
If valve lash is in the ball park, and they're all moving, then I'd pull the head and take a look. Make sure the head gasket isn't blown apart.
Do a leak test on the head. Put the head on its side and fill the exhaust/intake ports with kerosene. Watch the valves. If kerosene is dripping past a valve, it's too worn to seal.

Corn products were harvested for grain, and for ensilage (we always just called it 'silage'). Silo Filling Time On dairy farms back in the 30's and into the first half of the 40's, making of corn silage was done with horses pulling a corn binder producing tied bundles of fresh, sweet-smelling corn plants, nice green leaves with ear; the
