Oil flow into Toro 20624 air box

I picked up this 4-cycle GTS Toro for next to nothing. Cleaned all the wet, soggy, air filter debris out of the air box and the carb, cleaned the carb, and it fired right up, easily. Runs well on full choke--for a while, but won't run at all, off of full choke.

Didn't take long to see a pretty good flow of oil from the crankcase into the air box and then down to the carb intake. The parts diagram looks like there is a reed valve that feeds that hose to the airbox, but I can't tell for sure. Is it likely that's the problem? Get to it by removing flywheel??

Here's a pic of the hose, just above the fuel line.

Thanks!

Access to the breather reed valve is under the flywheel. Make sure your oil level isn't to high on the dip stick.

Experience is something you don't get until just after you need it.

Here's what I found. I don't SEE much wrong with the steel plate, and it seems to be laying flat but then again I don't really know exactly what I'm looking for. Thoughts?

Is the spark plug oil soaked ? While it's out, do a compression test with a good gauge...If don't have...borrow at Advanced Auto...
